The upsides of electromagnetic clutches

Electromagnetic clutches are flange-mounted, normally a two-piece construction, typically mounted directly on to the pump, states jbj Techniques.

Solid forged rotor

A one-piece solid forged rotor means no chance of internal parts separation, states the company. "The rotors also have an even wall thickness around the coil, which gives optimum flux distribution, maximising 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 jbj's special long-life grease, "which has shown a significant improvement in life over other standard high temperature greases".

E-coating

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 harsh environments.

Advantages of use:

• Electrically remotely actuated
• Reduced power consumption from engine
• Extended pump life
• Lower operator cost
• Simple installation
• Operator convenience/safety
• Cold weather starting.
