Well pumps by type of working part. A screw pump is one of the types of submersible pumping equipment. Pumps of this series are designed for pumping clean water from wells and reservoirs that meet the technical operating conditions of the pump. Screw pumps have good pressure characteristics. The pumps can withstand long-term loads well. If sand, chalk, or silt gets in with water, the auger parts wear out and require replacement.
