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.
