Monster 12 GPM Bare Pump - 1hp, 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 1HP and 3450 RPM, producing 12 GPM. The higher RPM makes this configuration well suited for light to medium viscosity fluids where fast transfer rates are the priority and the pump will be wired directly.

If you need a plug-and-pump portable unit with a handle and pre-wired switch, see the Monster 12 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, and other medium viscosity fluids.

The Motor

Stock US-Made Baldor motor, 1HP, 3450 RPM, 120/230V 60Hz. Shipped without switch, plug, or wiring. Requires hardwiring by a qualified electrician.
