Industrial Centrifugal Pump 3,750 L/min 80m — CMG 80-250B
-
HIGH-EFFICIENCY INDUSTRIAL DISCHARGE: Delivers an enormous water flow rate up to 3750 L/min (225 m³/h) with a high pressure lift head up to 80 meters (8 bar), supplying massive volume for large industrial plants, municipal waterworks, and fire-fighting networks.
-
OPTIMIZED ENERGY SAVINGS & IE3 COMPLIANT: Powered by a heavy-duty 45 kW (60 HP) 3-phase IE3 high-efficiency motor that maximizes fluid dynamic output per kilowatt, significantly cutting electrical energy bills during long continuous pumping cycles.
-
STANDARD EN 733 MONOBLOC DESIGN: Built with a stub-shaft and bracket for coupling to standard industrial motors in full compliance with EN 733 European hydraulic standards, supplied standard with counter-flanges for quick pipe connection.
-
HEAVY-DUTY CAST IRON & STAINLESS STEEL SHAFT: Engineered for extreme duty with a solid cast iron pump body and motor bracket, paired with a high-grade AISI 316 stainless steel motor shaft end and ceramic-graphite-NBR mechanical seal.
-
VERSATILE INDUSTRIAL TEMPERATURE & PRESSURE: Safely handles clean liquids at temperatures from -10°C to +90°C and supports maximum operating pressures up to 10 bar with IPX5 waterproof protection.
Product information
The Pentax CMG 80-250B is a heavy-duty Italian monobloc horizontal centrifugal electric water pump designed in full compliance with EN 733 standards. Specifically built for high-capacity industrial water supply, pressure boosting, municipal networks, and primary fire-fighting systems, it combines massive hydraulic output with structural durability.
Driven by a 45 kW (60 HP) 3-phase 400/690V 50Hz 2-pole IE3 induction motor, the CMG 80-250B delivers a high flow volume up to 3750 L/min at a maximum pressure lift head of 80 meters. The monobloc construction features a stub-shaft and coupling bracket for seamless standard motor integration, while counter-flanges come included as standard for easy installation into flanged industrial piping.
Built to perform under tough conditions, the pump incorporates a heavy-duty cast iron pump body and seal plate, an AISI 316 stainless steel shaft end, a ceramic-graphite mechanical seal, and IPX5 splash protection. Capable of handling temperatures from -10°C up to +90°C at operating pressures up to 10 bar, the Pentax CMG 80-250B offers customization options with cast iron, bronze, or AISI 316 stainless steel impellers for maximum chemical and mechanical endurance.
Impeller Material Comparison (Cast Iron vs. Bronze vs. AISI 316):
-
Cast Iron (Standard): Economical choice for clean water and regular daily operations.
-
Bronze (Optional): Zero seizure risk during long standby (ideal for fire-fighting), plus superior resistance to sea water, salts, and cavitation.
-
Stainless Steel AISI 316 (Optional): Maximum chemical, acid, and abrasion resistance for aggressive industrial fluids and high hygiene standards.
Note: Supplied standard with counter-flanges. Suitable for clean liquids in industrial pressurization, fire-fighting systems, and municipal water supply.
