Selecting Your Motor Enclosure

The pump models SSP, and SSPC are mounted on standard C-Face 56J frame motors. These motors are typically known as jet pump motors, as they were originally designed for shallow well jet pumps. The type of motor enclosure you desire depends on where you plan to put your pump.

Dripproof Motors (ODP)

An open motor in which the ventilating openings are so constructed that drops of liquid or solid particles falling on it, at any angle not greater than 15 degrees for the vertical, cannot enter either directly or by striking and running along a surface of the motor.

Totally Enclosed Motors (TEFC)

Totally enclosed motors are suitable for use in humid environments or dusty, contaminated atmospheres. TEFC motors are cooled by external means that are part of the motor, but are not in the internal workings of the motor.

Totally Enclosed Non-Vented Motors (TENV)

A motor so enclosed as to prevent the free exchange of air between the inside and outside of the case but not sufficiently enclosed to be termed air-tight, and dust does not enter in sufficient quantity to interfere with satisfactory operation. Cooling is by means of a fan or fans integral with the machine but external to the enclosure.

Explosion Proof Motors (XPRF)

A totally enclosed motor whose enclosure is designed and constructed to withstand an explosion of a specified gas or vapor which may occur within it and to prevent the ignition of the specified gas or vapor surrounding the motor by sparks, flashes, or explosions of the gas or vapor which may occur within the motor housing.

Washdown Duty Motors (W)

Designed for use in extremely moist or chemical environments, but not for hazardous locations. A motor so enclosed that it will exclude water applied as a stream from a hose, except that leakage may occur around the shaft provided it is prevented from entering the oil reservoir and provision is made for automatically draining the motor. The drain may be a check valve or a tapped hole at the lowest part of the frame which will serve for application of a drain pipe.
