Pump Limitations
Temperatures
Table 1: Temperature Limitations
Maximum Fluid and Ambient Operating Temp
203°F (95°C)*
Minimum Fluid and Ambient Operating Temp
-40°F (-40°C)
Maximum Ambient Storage Temp
257°F (125°C)
Minimum Ambient Storage Temp
-40°F (-40°C)
* If the intended application fluid temperature exceeds 95°C, installation must be
reviewed and approved by EMP to ensure warranty coverage. See Appendix A
for the Installation Approval checklist.
NOTE: Over-temperature Protection
If the internal electronics operating temperature exceeds 266°F (130°C) the pump will shut off and stay off until the
temperature drops to 257
°
F (125
°
C). At 95
°
C fluid temperature the pump controller is operating near the 130°C
electronics temperature threshold.
Vibration
Vibration exceeding the EMPTS009 profile can shorten pump life, potentially leading to PCB and motor shaft
failures. If you are unsure of your vibration profile for a given installation please contact EMP to ensure
warranty coverage.
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.
Orientation
Each pump part number has a specified and approved orientation. If the pump is not properly installed several
failure modes could potentially result. Please reference the Pump Orientation section of this document for
installation guidelines. If you have any questions regarding pump orientation please contact EMP to ensure
warranty coverage
