Page 10: Pump Limitations
Environment Environment cleanliness is crucial to pump life. The WP29 and WP32 are certified with an IP67 rating but debris collection in the weep pocket can lead to premature seal failure (See figure below). Shielding may be required to ensure debris does not enter the weep hole. If you have any questions regarding your installation contact EMP to ensure warranty coverage. -

The configuration will be forced to have a 3000 rpm pump speed limit. “Inlet B” is also restrictive, and will require the WP29 and WP32 pump speeds to be limited to 3500 rpm, where “Inlet C” remains in the safe operating zone for all measured pump speeds and has no special limitations. -

Page 18: Dual Orientation
Incorrect Pump Orientation and Reasons The WP29 and WP32 contain a mechanical seal; 0.1cc/hr may weep past the seal as a part of normal operation. To properly collect the weepage pump orientation is important. Too steep of an angle will not allow the fluid to collect in the weep pocket and evaporate off and the pump may appear to be leaking when in fact it is operating as designed. -
Page 19: Physical Inspection
NOTE: Mechanical Seal COOLANT MAY BE SEEN OUTSIDE THE EMP WP29 ELECTRIC WATER PUMP. design requires fluid between the shaft and the seal material. This fluid vaporizes and passes the seal, venting through the weep collection pocket. As the seal wears in, the amount of venting decreases but never to zero. -
