HCP 32GF21.5 Grinder Pump – 2 HP, 208/240V, 83.7 GPM

Heavy-Duty Submersible Grinder Pump for Wastewater Systems and Sewage Transfer

Product Overview

The HCP 32GF21.5 is a submersible dry motor pump engineered for demanding sewage applications. It effectively grinds solids into fine particles using a high-hardness cutting system, making it suitable for residential and commercial wastewater drainage. Constructed with durable cast iron components and double mechanical seals, this HCP grinder pump ensures reliable operation in pressure sewage systems.

Key Benefits of this Grinder Pump

• Grind household waste into fine slurry using a SUS440C radial cutter and cutter ring.
• Handles solids-laden sewage efficiently with a vortex impeller designed to reduce clogging.
• Ensures long-term durability with a corrosion-resistant radial cutter pump design hardened to 55-60 Rockwell C.
• Prevents motor burnout with an integrated automatic cut protector sewage pump feature.
• Protects against water intrusion with double mechanical seals and an epoxy resin cable base.
• Operates efficiently in pressure sewage systems with high torque capacitor starting on single-phase models.

Key Features of HCP 32GF21.5 Grinder Pump

Hardened Cutter for Solids

The grinder mechanism features a SUS440C radial cutter and cutter ring hardened to 55-60 Rockwell C, ensuring superior grinding of solid waste.

Non-Clog Vortex Impeller

The vortex impeller design creates a whirlpool effect that allows slurry to pass through without clogging the pump, maintaining consistent flow.

Double Mechanical Seals

An abrasion-resistant double mechanical seal system, manufactured with abrasion-resistant materials including silicon carbide., provides maximum sealing protection for the motor.

Submersible Dry Motor

High-efficiency dry motors feature stator coils treated with insulating varnish to ensure insulation and durability during continuous operation.

Auto-Cut Protector

The automatic on/off motor protector prevents damage from high temperatures or excess amperage draw, extending the life of this grinder pump.

Performance Overview

This cast iron pump provides high head performance, making it ideal for pressure sewage systems. The 2 HP single-phase grinder pump models feature a capacitor start design that delivers significantly higher starting torque than standard capacitor motors. With peak flow rates of approximately 83.7 GPM, these single-phase units are effective for transferring wastewater over long distances or to high elevations.
