» Extended pump life.
» Lower operator cost.
» Simple installation.
» Operator convenience/safety.
» Cold weather starting.

Ideal for pump operation. These are flange mounted, normally a two piece construction clutch typically mounted directly on to the pumps.

Solid forged rotor.
A one piece solid forged rotor means no chance of internal parts separation. Our rotors also have an even wall thickness around the coil which gives optimum flux distribution, maximizing torque.

Different coil voltages available.
Although 12 volt is the most common, 24 volts can also be made available. Depending upon the quantity, other specialty voltages can be made.

High temperature, longer life grease.
All models include our special long life grease which has shown a significant improvement in life over other standard high temperature greases.

Where possible, all parts in the clutch are e-coated to give maximum corrosion protection.

High temperature epoxy coil.
To help prevent failure from both vibration and outside contaminants, all coils are sealed in the coil shell with a high temperature epoxy coating.

Forged machined pulley.
All models in this section use a heavy duty machined pulley. A stronger pulley resists damage due to abusive environments.
MMC Clutch Series for Marine & Hydraulic Pump Applications.
MMC series electromagnetic clutches are designed for use with hydraulic pumps, many of which are used in marine winch drives. Typically flange or plate mounted, they engage and disengage the pump.
