Self-priming pumps

This category includes Calpeda self-priming pumps for water supply, well water extraction, pressure boosting, irrigation, drainage and a wide range of domestic, commercial and industrial applications.

The range covers different pump technologies – from self-priming jet pumps and liquid ring pumps to centrifugal pumps with open impellers and horizontal multistage self-priming centrifugal pumps. This allows different requirements for flow rate, head, pumped liquid, materials and supply voltage to be matched to the application.

Self-priming pumps for wells, water supply and pressure boosting
Jet pumps with built-in ejector
Multistage self-priming centrifugal pumps for higher delivery heads
Liquid ring pumps for applications involving air or gas in the pumped liquid
Open-impeller centrifugal pumps for clean or slightly dirty water
Cast-iron, bronze and stainless-steel versions
Single-phase and three-phase motor versions available

This category includes the Calpeda A, CA, MXA, NG, NGL and NGX series. When selecting the appropriate pump, the required flow rate, delivery head, suction lift, pumped liquid, material, connection size and supply voltage should be considered.
