Industrial Centrifugal Pump 350 L/min 22.8m — CM 32-160C
-
HIGH-EFFICIENCY INDUSTRIAL FLOW: Delivers a maximum water flow rate up to 350 L/min (21 m³/h) with a pressure lift head reaching 22.8 meters (2.28 bar), optimizing hydraulic delivery for civil and agricultural systems.
-
OPTIMIZED ENERGY SAVINGS: Precision-balanced monobloc hydraulics ensure maximum pumping efficiency per kilowatt, helping reduce overall electricity costs for continuous 1.5 kW motor operations.
-
STANDARD EN 733 FLANGED DESIGN: Built in strict compliance with EN 733 European standardized dimensions, allowing effortless direct integration and rapid maintenance inside industrial flanged pipe networks.
-
HEAVY-DUTY CAST IRON & STAINLESS STEEL SHAFT: Constructed with a rugged cast iron pump body and seal plate, paired with an AISI 304 stainless steel motor shaft extension and a 20 mm ceramic-graphite-NBR mechanical seal.
-
VERSATILE TEMPERATURE & PRESSURE TOLERANCE: Safely processes clean liquids from -10°C to +90°C under operating pressures up to 10 bar with IPX5 waterproof protection and Class F motor insulation.
Product information
The Pentax CM 32-160C (single-phase) and CMT 32-160C (three-phase) are commercial-grade monobloc horizontal centrifugal electric water pumps designed according to EN 733 standards. Built for industrial water supplies, pressure boosting, heating, HVAC cooling, agricultural irrigation, and fire-fighting systems, they deliver reliable hydraulic force in a standardized, compact footprint.
Powered by a 1.5 kW (2 HP) 2-pole induction motor, the CM 32-160C moves up to 350 L/min across a head range of 14 to 22.8 meters. The EN 733 monobloc layout simplifies installation and servicing within standardized flanged piping setups.
Engineered for continuous performance and low energy draw, the pump features a heavy cast iron casing, an AISI 304 stainless steel shaft extension, ceramic-graphite-NBR seals, and IPX5 moisture protection. Capable of handling liquid temperatures from -10°C to +90°C at system pressures up to 10 bar, the Pentax CM 32-160C provides versatile impeller configuration options in cast iron, bronze, or AISI 316 stainless steel.
Impeller Material Comparison (Cast Iron vs. Bronze vs. AISI 316):
-
Cast Iron (Standard): Ideal, budget-friendly option for clean water and standard daily pumping schedules.
-
Bronze (Optional): Prevents lock-up/seizure after long idle periods (perfect for standby/fire pumps) and offers high resistance to sea water and cavitation.
-
Stainless Steel AISI 316 (Optional): Offers maximum durability against aggressive chemicals, mild acids, and abrasive fluids.
Note: Suitable for clean water and non-aggressive liquids in heating, cooling, irrigation, and civil applications. Optional counter-flanges sold separately.
