-
STANDARD EN 733 BARE SHAFT DESIGN: Features a free-standing bearing bracket and drive shaft for easy flexible coupling to electric or diesel motors, allowing fast maintenance without disconnecting system piping.
-
HEAVY-DUTY CAST IRON & AISI 316 SHAFT: Built for intense service conditions with a cast iron pump body, cast iron seal plate, 20 mm ceramic-graphite-NBR mechanical seal, and a high-grade AISI 316 stainless steel pump shaft end.
-
VERSATILE INDUSTRIAL TEMPERATURE & PRESSURE: Safely handles clean liquids at temperatures from -10°C to +90°C under operating pressures up to 10 bar for heating, cooling, irrigation, and primary fire-fighting installations.
Product information
The Pentax CA32-160C is a heavy-duty, bare shaft horizontal centrifugal pump end engineered in strict compliance with EN 733 European standards. Specifically built for fire-fighting, it provides supreme hydraulic durability.
Designed as a bare shaft pump unit (without motor), the CA32-160C connects via a flexible coupling to standard 2-pole electric motors (including high-efficiency IE3 motors) or diesel engine drivers. It features a DN50 suction port and DN32 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 20 mm ceramic-graphite-NBR mechanical seal. Handling fluid temperatures from -10°C to +90°C, the Pentax CA32-160C 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.
