Selecting Your Motor Enclosure

The pump models 7SP 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):

• Dripproof motors have open enclosures. They are generally used indoors or in relatively clean atmospheres. Dripproof motors have ventilating openings. These openings are constructed in a fashion that allows drops of liquid or solid particles to fall on the motor at an angle less than 15 degrees without entering the motor.

Totally Enclosed Motors (TEFC) / Totally Enclosed Non-Vented Motors (TENV):

• Totally enclosed motors are suitable for use in humid environments or dusty, contaminated atmospheres. Totally enclosed non-ventilated motors (TENV) are not cooled by external means. 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 air over motors are totally enclosed non-ventilated motors that need to be sufficiently cooled by external means.

Explosion Proof Motors (XPRF):

• Explosion proof motors are also TEFC or TENV motors. They are designed for applications in atmospheres that are hazardous and may contain explosive gases or dusts.

Washdown Duty Motors (W):

• Washdown duty motors enable the motor to be completely sprayed by liquid without malfunctioning. This does not allow for the motor to be submerged.
