SM self-priming pumps
Applications
SM self-priming pumps are designed for pumping non-aggressive liquids, except fuels, within the corrosion resistance limits of materials used for their construction and liquids containing trace amount of non-grindable solid particles of up to 0.5 mm in size. The advantage of SM pumps is their ability to automatically remove air from the suction pipeline after their single priming with pumped liquid without the need of suction pipeline priming.
SM pumps can be used for:
- water supply from wells or natural/artificial tanks,
- rainwater utilization,
- garden watering,
- car washing,
- use in domestic hydrophores,
- industrial purposes.

Design
SM self-priming compact rotodynamic circulation pumps with side channel are driven by flange motors on feet. The extended motor shaft end is made of a corrosion-resistant steel alloy. Pump impellers are seated on the extended motor shaft end, their position is restricted by members side surfaces. In suction housing a non-maintenance and leak-free front seal is mounted on the shaft.
Features:
- many years of reliable operation and easy access to replacement parts guaranteed,
- execution of individual requirements and products adjusted to customer's needs,
- permanent technical supervision as well as guarantee and post-guarantee service,
- low procurement and operation costs,
- relatively long life in difficult operational conditions.
