Industrial Centrifugal Pump 2,200 L/min 19.2m — 4CA 80-250B
HIGH-EFFICIENCY CONTINUOUS OPERATION: Features a slow-speed 1450 RPM (4-pole) hydraulic setup that delivers water flow up to 2200 L/min with smooth pressure output up to 19.2m.
MAXIMUM ENERGY SAVINGS WITH LOW-POWER MOTOR: Driven by an ultra-efficient 7.5 HP 5.5kW 4-pole electric motor on a steel baseplate, designed to operate continuously with minimal electrical kilowatt usage.
QUIET, LONG-LIFE HEAVY-DUTY OPERATION: The 1450 rpm slow rotation dramatically reduces mechanical wear, noise, and vibration, providing long, maintenance-free service life in commercial HVAC and water circulation systems.
ROBUST INDUSTRIAL MATERIALS: Built with a cast iron pump body, cast iron bracket, AISI 316 stainless steel pump shaft end, and a mechanical seal for complete structural reliability.
EN 733 STANDARDIZED TURNKEY SYSTEM: Delivered fully assembled on a rigid baseplate with flexible drive coupling and protective guard, operating safely at pressures up to 10 bar and temperatures from -10°C to +90°C.
Product information
The Pentax 4CA80-250B+MOT132S is a commercial-grade, baseplate-mounted 4-pole horizontal centrifugal pump unit constructed in full compliance with EN 733 European hydraulic standards. Specially designed for continuous circulation in HVAC heating and cooling loops, municipal water transfer, agricultural irrigation, and industrial process systems, this unit emphasizes whisper-quiet operation and high energy efficiency.
Equipped with a 5.5 kW (7.5 HP) 4-pole IE3 electric motor running at 1450 RPM, it delivers up to 2200 L/min with a pressure head up to 19.2m. The complete unit comes pre-assembled on a steel baseplate connected via a flexible shaft coupling with a safety guard, protecting components from axial misalignment.
Built for heavy continuous duty, the pump features a cast iron pump body and seal plate, an AISI 316 stainless steel shaft end, and a mechanical seal. Handling fluid temperatures from -10°C to +90°C at system pressures up to 10 bar, the Pentax 4CA+MOTOR series supports customizable options including cast iron, bronze, or AISI 316 stainless steel impellers, counter-flange kits, and gland packing seals.
Impeller & Configuration Comparison:
Cast Iron Impeller (Standard): Excellent, cost-effective option for clean water in daily circulation systems.
Bronze Impeller (Optional): Prevents rust lock-up during long standby periods and delivers superior resistance to sea water and cavitation.
Stainless Steel AISI 316 Impeller (Optional): Offers maximum corrosion and chemical resistance for harsh technical liquids.
Gland Packing (Optional): Traditional braided packing alternative to mechanical seals for environments with sand or particles.
Note: Fully assembled on baseplate with 4-pole motor, flexible coupling, and coupling guard included.
