Materials
SS316
Heads, plungers, clean-water hardware
Wide mechanically. Chloride SCC risk rises with heat.
Temperature windows below describe the listed materials. Liquid temperature for the pump still depends on the head, the chemical and the pressure, and is confirmed on the quote.

FAQ
Why are there no prices?
This is an inquiry catalog. Duty, materials and certificates change the offer. Engineering replies within one business day.
What flow and pressure does this model cover?
Series ends: up to 75 L/h and up to 200 bar. Those ends are separate. Where a model table is shown, each row pairs flow with that size's back pressure. The duty is confirmed on the quote.
Which wet-end materials are listed?
SS304 / SS316. Confirm medium, concentration and temperature on the quote.
Which certificates do you hold?
Certificates are confirmed on the quote. They are not listed on this site. EAC is arranged per order.
