electromagnetically operated and driven through a
special flange mount which adapts to a universal
joint flange. When current is applied to the clutch
coil, the armature is pulled against the rotor,
causing the clutch to engage. This clutch employs
a sealed bearing and it is maintenance free and
never needs lubrication. Installation is to be made
in accordance with this service sheet. A
connection diagram and troubleshooting
information are also included.

Failure to follow these
instructions may result in product
damage, equipment damage, and
serious or fatal injury to personnel.

Installation

1. Pump clutches are furnished with either a 13
tooth spline or a keyed drive. For splined hub
versions, match the splines to those on the
pump shaft and push the clutch onto the shaft.
With the keyed shaft version, insert the key into
the shaft keyway, match the hub slot to the key
and push the clutch onto the shaft.

Electrical Connection

1. Voltage Requirement

This clutch is 12 or 24 VDC.

2. Current Draw (amps)

The specific current draw for this clutch is
listed in the product specification. A minimum
of 10 amps current should be available to
operate this clutch.

3. Connection

Please refer to the adjacent diagram for proper
connection. Note that one wire is to be
connected to a DC power source. Either wire
may be positive or negative. Select one wire
and attach it to a ground connection or a
negative battery terminal. Attach the remaining
wire to an on/off switch. The switch must be
on a (minimum 10 amp) fused circuit to protect
the electrical system in case of a short circuit.

2. With the clutch on the shaft, push it firmly
against the pump bracket. Complete the
installation procedure in the reverse order for
removing the old clutch.

3. A drive shaft with a universal joint is attached

clutch are dimensioned to correlate with
“Spicer” type drive shaft flange connections.
The pump clutch is connected to the other end
of the shaft. Drive shaft alignment must be

within three degrees of straight.

A burnish cycle is required to achieve full rated
torque. With the power input rotating at normal
speed and the pump set at minimum load, cycle
the clutch on and off 50 times at the rate of 10
cycles per minute, which is three seconds run
time and three seconds off time. A new clutch
may emit a short squeal when initially engaged.
