Product information
The Pentax CA65-200B is a heavy-duty, bare shaft horizontal centrifugal pump end engineered in strict compliance with EN 733 European standards. Specifically built for civil systems, it provides supreme hydraulic durability.
Designed as a bare shaft pump unit (without motor), the CA65-200B connects via a flexible coupling to standard 2-pole electric motors (including high-efficiency IE3 motors) or diesel engine drivers. It features a DN80 suction port and DN65 delivery port, delivering maximum hydraulic efficiency at operating pressures up to 10 bar.
Engineered for long-term continuous operation, the pump incorporates a heavy cast iron casing, cast iron seal plate, AISI 316 stainless steel shaft end, and a 28 mm ceramic-graphite-NBR mechanical seal. Handling fluid temperatures from -10°C to +90°C, the Pentax CA65-200B offers versatile customization options with cast iron, bronze, or AISI 316 stainless steel impellers, as well as gland packing seal upgrades.
Impeller & Configuration Comparison:
Cast Iron Impeller (Standard): Economical choice for clean water and standard daily industrial pumping.
Bronze Impeller (Optional): Eliminates rust seizure during long standby periods (ideal for fire pumps) and provides exceptional resistance to sea water and cavitation.
Stainless Steel AISI 316 Impeller (Optional): Maximum chemical, acid, and abrasion endurance for harsh industrial liquids.
Gland Packing (Optional): Traditional braided rope packing alternative to mechanical seals for high-sand or slurry environments.
Note: Bare shaft pump only. Motor, coupling, baseplate, and optional counter-flanges sold separately.
