The CKR is a compact self-priming pump that copes with irregular flow or liquid mixed with air. The cast iron pump body has a stainless steel front surface, and the patented aluminium motor bracket (IT1243605) has a brass anti-lock cover, so the impeller can’t seize through oxidation.

Frequently asked questions

CKR 90 or CKR 100?

The CKR 90 gives more head: up to 55 m at up to 50 l/min. The CKR 100 gives more flow: up to 70 l/min at up to 37.5 m. Both are 0.75 kW.

How is it different from the CK?

The CKR adds Pedrollo’s anti-lock design (a stainless steel surface in the pump body and a brass-covered motor bracket) so the impeller can’t seize, and it is rated for clean water as well as diesel.

Single or three-phase?

Both sizes come as single-phase CKRm (230 V, IE2) and three-phase CKR (400 V, IE3).
