List of products
Pump unions allow quick removal of a circulation pump from the pipeline without draining the entire system. Check valves from the EURA SPRINT series are supplied in sizes from 1/2" to 3" with an increasing flow coefficient Kv from 2.00 to 192.00, allowing selection according to the required flow rate and pipe size.
Suction strainers protect the pump suction line from drawing in debris and coarse sediment from a tank or well. The category also includes check valves with a soft seal on the disc for horizontal installation in the pipeline.
Frequently Asked Questions
- What is the flow coefficient Kv? It indicates the water flow rate in m³/h at a pressure loss of 1 bar – a higher Kv value means lower valve resistance at a given flow rate.
- Why use a union instead of screwing the pump directly? A union allows the pump to be easily removed for servicing or replacement without dismantling the surrounding pipework.
- Is a check valve required for every pump installation? A check valve is recommended especially where backflow of the medium needs to be prevented when the pump stops or fails.
