Frequently Asked Questions
What size of solids can the pump handle?
Our free-passage impellers typically pass solids up to [ 50 mm]. For higher solid loads, ask about our cutter-type option.
Can the pump run dry?
The pump is designed for submerged duty. A low-level float switch or level sensor is recommended to avoid dry running.
Do you supply pumps with float switches and control panels?
Yes - we can supply complete sets, including float switches, control cabinets, and coupling systems.
Note: Test reports and performance curves are provided with every shipment.
