AISI 316 Stainless Centrifugal Pump — CAX 40-250B
OPTIMIZED FOR COOLING SYSTEMS: Engineered to EN 733 European dimensions, the CAX40-250B delivers reliable, high-volume fluid transfer and steady pressure perfectly suited for demanding commercial systems.
MAXIMUM ENERGY EFFICIENCY: Compatible with standard and premium IE3 high-efficiency electric motors. This flexibility allows you to optimize your system's energy draw and significantly reduce long-term electricity costs.
100% AISI 316 STAINLESS STEEL BUILD: Constructed completely from premium AISI 316 stainless steel—including the pump casing, impeller, and shaft. This ensures ultimate rust and corrosion resistance, making it safe for aggressive chemicals, pure water, and food-grade liquids.
VERSATILE BARE SHAFT DESIGN: Features an independent bearing bracket and drive shaft for easy baseplate mounting. Equipped with DN65 In / DN40 Out connections, it easily couples with electric or diesel motors for maximum installation flexibility.
HEAVY-DUTY INDUSTRIAL PROTECTION: Built to last in severe environments. It features a robust Ceramic-Graphite-NBR (Optional: Gland Packing) seal, safely handling operating pressures up to 10 bar and extreme liquid temperatures ranging from -10°C to +90°C.
Product information
The Pentax CAX40-250B is a heavy-duty, bare shaft horizontal centrifugal pump end constructed entirely from AISI 316 stainless steel in compliance with EN 733 European standards. Built for severe industrial environments, chemical liquid transfer, food and beverage processing, reverse osmosis (RO) pre-treatment, and high-purity water supply, it offers supreme chemical and corrosion endurance.
Designed as a bare shaft pump unit (without motor), the CAX40-250B features a DN65 suction port and DN40 delivery port. It connects via flexible couplings to standard electric motors (including high-efficiency IE3 motors) or emergency diesel drivers on customized baseplates.
Constructed for maximum longevity under harsh operating conditions, the pump incorporates an all-AISI 316 stainless steel casing, seal plate, impeller, and shaft extension, along with a robust 28 mm Ceramic-Graphite-NBR mechanical seal. Supporting operating pressures up to 10 bar and handling temperatures from -10°C to +90°C, the Pentax CAX series offers optional upgrades such as AISI 316 counter-flange kits and gland packing seals for sand or slurry applications.
Note: Bare shaft pump only. Motor, baseplate, coupling, and optional counter-flanges sold separately.
