Monster 25 GPM Bare Pump - 2hp, 120/230V 60HZ

Bare pump assembly. No switch, no plug, no handle. This unit ships ready for hardwiring into a custom skid, control panel, or permanent installation.

This configuration pairs the GSM25 cast-iron pumphead with a stock US-Made Baldor motor at 2HP and 3450 RPM, producing 25 GPM. The additional horsepower over the 1HP configuration provides more torque headroom for medium viscosity fluids or applications where the pump runs under sustained load. Intended for permanent installations where the pump will be wired directly into a control system or panel.

If you need a plug-and-pump portable unit with a handle and pre-wired switch, see the Monster 25 GPM Portable Pump series instead.

The GSM25 Pumphead

The GSM25 is a direct-drive, cast-iron positive displacement gear pumphead with helical-cut steel gears. It is self-priming, delivers fast and pulseless fluid transfer, and relies on the fluid itself for internal gear lubrication. Viton seals provide compatibility with vegetable oils, motor oils, gear oils, and other high-viscosity fluids.

The Motor

Stock US-Made Baldor motor, 2HP, 3450 RPM, 120/230V 60Hz. Shipped without switch, plug, or wiring. Requires hardwiring by a qualified electrician.
