The Pentax CR75 is a robust centrifugal pump from the CR series designed for medium-delivery applications such as irrigation, domestic water supply and light industrial use. Built with a cast-iron body and motor bracket, the CR75 offers reliable performance and long service life.

Key features

• Single-phase 230V induction motor with thermal protection and insulation class F — suitable for standard domestic and agricultural power supplies.
• Power: approx. 0.75 HP (0.59 kW); flow range roughly 50–240 L/min with a head range around 14.3–7 m depending on model/curve.
• Open impeller design (Noryl® or brass options) allows passage of small solids (max Ø 10 mm) — ideal for handling slightly dirty water or agricultural runoff.
• Mechanical seal: ceramic-graphite-NBR for durability and good resistance to wear. Maximum pump body gasket rating up to 6 bar.
• Protection rating IPX4 (50Hz versions) / IP44 (60Hz versions) — splash resistant for outdoor installations when mounted correctly.

Applications & benefits

Designed as a high-flow, low-pressure centrifugal pump, the CR75 is well suited for garden and farm irrigation, pressure boosting, water transfer and simple clean-to-slightly-dirty water duties. The combination of cast iron construction, selectable impeller material, and proven mechanical sealing makes it a versatile choice for users seeking a durable Pentax pump with solids-handling capability.
