Barrel pumps from the Italian company FLUIMAC of the NETTUNE series are designed for transferring various types of liquids from cans, barrels, and euro-cubes. Pump tubes for the pumps are available in:

• polypropylene (PP): suitable for neutral, aggressive, and flammable liquids, specifically used for transferring aggressive chemicals such as acids, alkalis, or detergents with a maximum transfer medium temperature of 50°C;
• PVDF: suitable for highly aggressive liquids such as concentrated acids and alkalis, with a maximum medium temperature of 90°C;
• aluminum (AL): suitable for neutral and flammable liquids, mineral oils with a maximum viscosity of up to 1000 mPa and a maximum product temperature of 90°C;
• stainless steel AISI 316: used for all neutral and aggressive liquids such as diluted acids, alkalis, or detergents, as well as liquid food products, with a maximum transfer medium temperature of 90°C.

It is also very important to pay attention to the pump part configuration. There are cases when the material of the pump part is perfectly suitable for transferring the product, but for example, the seal or shaft does not withstand corrosion resistance.

One such example is the use of a polypropylene pump part for transferring hydrochloric acid with a concentration of only 5%. The result can be seen in the photo below.

An ideal solution for this task is to use a pump part with a shaft made of Hastelloy steel.

Hastelloy steel is used for transferring particularly aggressive liquids such as concentrated and diluted acids, alkalis, or detergents.

In our online store, you can purchase barrel pumps that will handle any task.

For pumping thick and viscous liquids, such as grease, bitumen, oil, foodstuffs and other high viscosity substances, specialised types of pumps are used, which have certain design features. Most of them are positive displacement pumps. They provide reliable operation under conditions of high load and high liquid density.

Main types of pumps for thick and viscous liquids

Gear pumps (gear pumps)

These are pumps with gears as the main working body. The gears are in constant engagement and, when rotating, create a low and high pressure zone, respectively, on the one hand, the product is sucked in and then moved between the gear teeth to the discharge zone.

The advantages of this type of pumping equipment include the ability to suck ‘dry’, without preliminary filling of the working chamber, high efficiency when working with viscous liquids, small size and compact design, reversible operation (ability to change the direction of pumping).

Among the disadvantages, it is worth noting the limited ability to pump liquids with a high content of abrasive particles, solid inclusions that can lead to pump jamming and rapid wear of working elements.

This group of pumps can be divided into two main subgroups:

• pumps with external gearing
• pumps with internal gearing

External gear pumps are easier to manufacture and maintain, but internal gear pumps can handle more viscous liquids.

Screw pumps

They consist of a screw-shaped rotor that rotates in a rubber casing, which moves the liquid in the axial direction. This type of pump is suitable for handling high viscosity liquids such as oil, resin, bard, detergents, hydrofuse, minced meat, etc. They provide a smooth and continuous flow.

By changing the screw pitch, cage diameter, and rotation speed, the pump can be tailored to almost any product.

Among the disadvantages are the high cost of manufacturing due to the complexity of the design, large dimensions (even low-capacity pumps are more than 1 m long), the cost of parts, and rapid stator wear in the presence of solid particles in the product.

Peristaltic (hose) pumps

In these pumps, the liquid is pumped through a flexible hose, with the hose remaining stationary during operation. The hose is sandwiched between the casing and rollers, which, as they rotate, crimp the hose, forcing the product through the hose.

They are often used for pumping aggressive, thick and abrasive liquids, particularly in the chemical and pharmaceutical industries.

Advantages:

They are suitable for pumping thick and abrasive liquids, do not foam the product, and there is no contact between the liquid and the moving parts of the pump, which significantly extends the pump's service life.

Disadvantages:

Quite low working pressure - usually about 1-2 atm.

Rapid wear of the hose, requiring frequent replacement.

Diaphragm (diaphragm, pneumatic) pumps

These pumps are based on the principle of changing the volume of the working chamber due to the reciprocating movement of the diaphragm.

The diaphragm is mounted on a pneumatic motor stem and driven by compressed air. The pump consists of two working chambers connected by a suction and pressure manifold to ensure uniformity of flow and pulsation. As a result, when one chamber is undergoing a discharge cycle, the second chamber is sucking the product.

The working chamber is equipped with gravity-type valves (i.e. the movement is due to gravity, there are no springs), which allows pumping a variety of products containing suspended particles.

Valves are conventional balls made of stainless steel, rubber or plastic that alternately close and open the entrance to the working chamber when the membrane moves.

The membranes are made of such materials as EPDM, PTFE, Santopren, NBR. The working chamber can be made of PP, PVDF, AL, AISI 304, AISI 316.

ECV pumps are widely used in Ukraine to extract water from artesian wells.

In every corner of Ukraine, in almost every village, town and city, these pumps have been indispensable for providing water supply to residents and virtually any production facility.

The pump marking consists of three capital letters ECV and numbers:

E - electric motor as a drive C - centrifugal action W - water (working medium).

These pumping units were manufactured in Ukraine at two plants - Kherson Electromechanical Plant and Berdiansk Azovenergomash Plant.

Due to certain circumstances, it is currently impossible to manufacture and supply these pumps, so our company decided to supply imported pumps, which can completely replace ESP pumps in terms of their hydraulic characteristics, and whose design, material and maintainability are much higher.

Our website presents the SD and SP series of downhole pumps.

Both series have an oil-filled motor that can be rewound. The connecting flange (adapter caliper) of the motor and pump unit is made according to the NEMA standard, which makes these motors universal and allows them to be used with pump units from other manufacturers (Pedrollo, Speroni, Wilo, Saer, etc.).

SD series pumps

The guide diffusers and impellers of the SD series pumps are made of durable PC, POM plastic, and the rest of the parts (motor casing, shaft, coupling, adapter caliper) are made of stainless steel.

The motor diameter is 4 inches, which means that such pumps can be installed in wells with a diameter of 120 mm or more.

SP series pumps

The flowing part of these models is made entirely of AISI 304 stainless steel, which allows these pumps to be used in mineral water wells.

The impellers are mounted to the shaft with tapered spacer bushings, and the compact stamped stainless steel diffusers contain a plastic bearing and a plastic guide ring, which guarantees high hydraulic efficiency.

The design of the pump unit does not include any spacers, adapters, washers, thrust rings or spacers, which makes repairing the pump simple and quick.

The motor diameter is 6 inches, meaning that these pumps can be installed in wells with a diameter of 150 mm or more.

For your convenience, the table below shows the respective SP and SD series pumps, which correspond to the ECV pumps in terms of hydraulic characteristics.

Advantages

• High performance: Diesel engines typically provide higher power and torque, allowing for efficient handling of heavy loads.
• Long service life: Diesel forklifts can run for longer periods of time without interruptions compared to electric forklifts, making them ideal for continuous operation.
• Durability: They are able to work in a variety of conditions, including outdoors and uneven surface conditions.
• Cost of operation: Currently, diesel fuel can be cheaper on the market compared to batteries for electric forklifts.

Disadvantages

• Emissions: Diesel engines produce harmful emissions, which can be a problem in enclosed spaces or in areas with strict environmental regulations.
• Noise: Using a diesel forklift can result in increased noise levels, which can be a disadvantage in quiet areas.
• Maintenance: Diesel engines require regular maintenance and can have higher maintenance costs than electric models.
• Weight: Diesel forklifts are generally heavier, which can affect their manoeuvrability in narrow aisles.

The choice of a 3.5 tonne diesel forklift truck depends on the specifics of your work. If you need a powerful, robust forklift for outdoor use or in difficult conditions, a diesel option may be ideal. However, if you work indoors and are concerned about emissions and noise, you may want to consider electric alternatives.

The cam pump is a type of positive displacement pump that is widely used in various industries, including food, pharmaceutical, chemical and cosmetic. The principle of its operation is based on the movement of fluid by means of two rotating cams, which are synchronised and create volumetric changes that ensure a continuous flow of the working medium. Such pumps have a number of advantages: they are easy to operate, capable of pumping liquids with high viscosity and do not damage the structure of the pumped material.

Cam pump design

The pump consists of a casing, two cams (rotors), drive shaft, seals and synchronising gears. The cams are specially shaped to create zones of fluid capture and movement within the pump chamber. They are often made of strong and corrosion-resistant materials (e.g. stainless steel), which ensures reliability and durability of the device even when working with aggressive or abrasive substances.

How it works

The operation of a cam pump starts with the rotation of the drive shaft, which drives the cams via synchronising gears. The cams rotate in opposite directions but do not touch each other. As they rotate, they create successive zones of expansion and contraction in the pump chamber.

Application of cam pumps

Cam pumps are in demand in applications that require gentle movement and minimal impact on the structure of the liquid. In the food industry, they are used to pump products such as yoghurts, jams, creams and syrups. In the pharmaceutical industry, they are used to transfer suspensions and various drugs that require gentle handling. In the chemical industry, they are used to pump viscous liquids such as oils, resins and gels.

A pneumatic diaphragm pump is a device that uses compressed air to move fluid. This type of pump is widely used in the chemical, oil, food, pharmaceutical and other industries, as it allows pumping high viscosity liquids, abrasive and corrosive liquids, as well as media containing solid particles. The principle of operation of a pneumatic diaphragm pump is based on the compression and expansion of the diaphragms, which create a vacuum to capture and eject the liquid.

Pneumatic diaphragm pump design

The pneumatic diaphragm pump has a simple but effective design consisting of:

• Body divided into two chambers (pneumatic and hydraulic);
• Two membranes connected by a common rod system;
• Air valve controlling the flow of compressed air;
• Inlet and outlet valves that regulate the flow of working fluid.

The pump casing is usually made of chemically resistant materials such as polypropylene, stainless steel or aluminium. The diaphragms are made of materials resistant to aggressive media such as Teflon or nitrile, making the pumps suitable for use with aggressive and abrasive substances.

The principle of operation

The basic principle of operation of a pneumatic diaphragm pump is based on the movement of compressed air between the chambers and the creation of a cyclic movement of the diaphragms. Let's take a closer look at the process:

• Compressed air supply: Compressed air enters one of the pneumatic chambers, which leads to displacement of the membrane towards the hydraulic chamber. The membranes move synchronously because they are connected by a common rod.
• Fluid entrainment: When one diaphragm compresses the hydraulic chamber, the other diaphragm creates a vacuum in the opposite chamber, allowing fluid to enter the pump through the inlet valve.
• Fluid Ejection: A membrane compressing the chamber forces fluid through the outlet valve, creating a steady flow of fluid.
• Transition of air to another chamber: The air valve switches the flow of compressed air to the opposite side, and the cycle repeats itself, ensuring continuous fluid movement.

Advantages and disadvantages of pneumatic diaphragm pumps

Advantages:

• Versatility: can pump liquids with high and low viscosity, including abrasive and aggressive liquids.
• Self-priming: the pumps are able to work without filling, which is especially important when moving environments with high requirements for cleanliness.
• Safety: due to the absence of an electric motor, the pumps are safe for use in explosive areas.
• Simplicity of design and maintenance, lack of complex mechanisms, which reduces operating costs.

Disadvantages:

• Noise during operation, as the pumps use compressed air, which may require additional noise reduction devices.
• High air consumption, which can increase operating costs under conditions of constant use.
• Pressure Limitation: These pumps typically operate within low to medium pressures, making them unsuitable for processes requiring high pressures.

Application of pneumatic diaphragm pumps

Pneumatic diaphragm pumps are used in a variety of industries:

• Chemical industry: for pumping aggressive acids and alkalis.
• Oil industry: for moving fuel, oils and other hydrocarbon liquids.
• Food industry: for pumping food products such as juices, sauces and viscous mixtures.
• Pharmaceuticals: for working with pharmaceutical viscous liquids that require careful handling.

Silica gel is used to drain the space inside the double-glazed windows of plastic windows. However, silica gel is not perfect for this purpose: even at zero temperature outside the window, condensation can be seen on the glasses. Crystalline aluminosilicates cope with the task much better – this is a molecular sieve. Read more about it in our article.

Molecular sieve for double-glazed windows: what is it and why is it needed?

A molecular sieve is a combination of silicon and aluminum oxides; they are pellets permeated with many pores, beads. Geologists better known it as "zeolites".

Their value lies in the fact that the pores mentioned above have a certain diameter; water vapor molecules pass through them, but gas molecules do not pass through them. Due to this ability to selectively absorb molecules, these clay-like lumps were called a "molecular sieve": they "filter out" water vapor from, say, argon, which is filled with double-glazed windows for better thermal insulation.

Molecular sieve for double-glazed windows: technical characteristics

Molecular sieve for double-glazed windows is available in the form of granules ranging in size from 0.5 to 2 mm. Synthetic aluminosilicates with pore sizes of 3 Angstroms are used.

The adsorption capacity of the molecular sieve is 17-20% (depending on the manufacturer). Bulk density – 700-770 kg/m3.

The consumption of molecular sieve for double-glazed windows depends on the width of the distance frame. The standard width of frames for plastic windows varies in increments of 1 mm (for wide frames – in increments of 2 mm and 4 mm) from 5.5 mm to 23.5 mm. So: 72 grams of aluminosilicates are poured into a 5.5 mm wide frame for each square meter of double-glazed window area; 348 grams are poured into a 23.5 mm wide frame. "sieves" for each sq. m double-glazed windows.
