Industrial Centrifugal Pump 5,500 L/min 83.7m — CMG 100-250B
HIGH-CAPACITY INDUSTRIAL WATER TRANSFER: Delivers an exceptional water flow rate up to 5500 L/min with a high pressure lift head up to 83.7 meters. Perfect for supplying massive water volume for demanding industrial plants, municipal waterworks, and pressurisation networks.
OPTIMIZED ENERGY SAVINGS & IE3 COMPLIANT: Powered by a heavy-duty 75 kW (100 HP) 3-phase IE3 high-efficiency motor. This maximizes fluid dynamic output per kilowatt, significantly cutting your 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. It comes supplied standard with counter-flanges for quick and easy pipe connection.
HEAVY-DUTY CAST IRON & STAINLESS STEEL SHAFT: Engineered for extreme duty and long life with a solid cast iron pump body, cast iron impeller, and motor bracket. It is paired with a high-grade AISI 316 stainless steel motor shaft end and a reliable ceramic-graphite-NBR mechanical seal.
VERSATILE INDUSTRIAL TEMPERATURE & PRESSURE: Safely handles clean liquids at temperatures ranging from -10°C to +90°C and supports maximum operating pressures up to 10 bar with secure IPX5 waterproof protection.
Product information
The Pentax CMG 100-250B 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 75 kW (100 HP) 3-phase 400/690V 50Hz 2-pole IE3 induction motor, the CMG 100-250B delivers a high flow volume up to 5500 L/min at a maximum pressure lift head of 83.7 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 100-250B 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.
