Safety
Warnings, Cautions & Notes
Three types of headings are used in this manual to stress your safety and safe operation of the WP29.
They appear in the text as follows:
WARNING:
THIS SYMBOL IS USED TO MAKE YOU AWARE OF AN UNSAFE CONDITION, HAZARD, OR PRACTICE THAT
CAN RESULT IN PERSONAL INJURY OR DEATH.
CAUTION:
THIS SYMBOL IS USED TO ALERT YOU TO A CONDITION OR PRACTICE THAT CAN CAUSE DAMAGE TO
THE WP29 AND WP32 OR THE VEHICLE, OR BOTH.

NOTE: Is used to provide additional information that requires special attention by the technician.
Product Safety Warnings
EMP cannot anticipate every possible circumstance that might involve a potential hazard. The safety messages in this
document, in related manuals, and on the product are therefore not all inclusive. If a tool, procedure, work method, or operating
technique that not specifically recommended by EMP is used, you must satisfy yourself that it is safe for you and for others. You should
ensure that the product will not be damaged or be made unsafe by the operation, maintenance, or repair procedures that you choose.
Ensure that all safety message and information messages are read and understood before installation, maintenance, or any
repairs are performed. The person who services the product may be unfamiliar with many of the systems on the product. It is
important to use caution when service work is performed. Knowledge of the vehicle system and operation are important before the
removal or disassembly of any component.
Make sure the vehicle is in neutral, the parking brake is set, and the wheels are blocked before doing any work or diagnostic
procedures on the WP29 and WP32, or vehicle.
Disconnect the main negative battery cable and/or switch the battery disconnect switch to the OFF position first before
installation or servicing.
Use extreme caution when working on systems under pressure (i.e. coolant, hydraulic fluids, air, etc…)
Make sure the work area is ventilated and well lit.
Make sure charged fire extinguishers are in the work area.
Reinstall all safety guards, shields, and covers after servicing the vehicle.
Make sure all tools, parts, and service equipment are removed from the engine compartment and vehicle after all work is done.
Do not apply power to the pump without fluid since most pumps are programmed to start when power is applied and the pump
seal will be damaged if run dry.
If CAN or Serial TTL control is not used the 6 pin DTM connector must be blocked off to prevent entry of water or dirt which will
result in damage to the pump. A block off plug EMP P/N 3250001030 can be purchased or one can be fabricated from the Deutsch
parts listed in the table on page 12

Performance
Pump Performance Curves
The pump performance curves shown in the illustrations below outline the maximum capability of the pump at
maximum speed of the pump. Following the installation guidelines will result in peak performance matching
the illustrated operation. Pump speed reduction will reduce the output capability.
The static pressure curve represents the pressure rise across the pump for a given flow. If the inlet pressure of
the pump is negative, the outlet pressure of the pump is reduced by the inlet suction. Be aware of this situation
in systems with little or no head pressure on the system.

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.

Inlet A Inlet B Inlet C LIMIT
In the WP29 and WP32 Pump Inlet Pressure Map, three inlet configurations are illustrated. “Inlet A”
configuration represents an inlet that is very restrictive, and any pump operation above 3000 pump rpm
will violate the minimum inlet pressure requirement. 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.
If the application has low outlet restriction, the pump is current limited and may not be able to reach the
anticipated pump speed. This speed limitation is a result of the motor controller protecting the
electronics from a condition where excessive heat may build up in the controller.

Plumbing
Recommended Plumbing
Pump Inlet must be plumbed using 25mm (1.0 inch) diameter hose and/or thin walled tubing from the fluid
supply to the pump inlet.
A restriction in the inlet plumbing is allowed as long as the flow diameter is not less than 17mm (0.75 inch) and
does not exceed 25mm (1.0 inch) in length.
Deviations from the Recommended Plumbing must meet the Inlet Requirements and be approved by
EMP Engineering. Please contact EMP customer service for installation review.
Mounting Screws
Mounting screws used should be M8 x 1.25 screws (qty=4). These must have a minimum thread engagement
of 0.50 inch (12.7 mm) and be tightened to a torque of 15 ft-lb (20N-m).
CAUTION: THE MOUNTING HOLES ARE TAPPED TO A DEPTH OF 0.59 INCHES (15MM). BE AWARE OF
THE BRACKET THICKNESS WHEN SELECTING THE FASTENER LENGTH TO ENSURE THAT THE FASTENER
WILL NOT BOTTOM OUT IN THE PUMP HOUSING.
Hose Clamps
When making the inlet and outlet hose connections to the pump it is strongly recommended to use SAE20CT
worm drive type hose clamps. Torque worm drive clamps to 45 in-lbs per SAE J1508.Spring type clamps are
not recommended.

(1): Peak current is based on the software current limit. 25 amps is the standard current limit for a 12V pump and 15 amps is the standard
current limit for a 24V pump for serial numbers > 07065826.
(2): The pump shuts down when the internal controller temperatures reaches 130˚C at this point the pump will stop running until the internal
controller temperature drops below 125˚C. Once the safe value is reached, the pump will restart. No ignition cycle is required to restart the
pump.
(3): The inrush current occurs when the controller first receives the required voltage on the ignition pin. This current inrush is due to the
charging of the bulk capacitors in the controller. The inrush current numbers are worst case. They were measured with a battery as the source
with a harness that was 3ft in length (very low source impedance). Anything done in the application to increase the source impedance will have
a significant (downward) impact on these numbers. This current is not generated every time the motor is started, but only when the ignition line
is first applied.

Wiring
Wire Sizing
- For complete connector body sealing the
ignition wire should be 16ga minimum and
the power and ground wires should be 12ga
minimum
Recommended Wiring Practices
- Wiring or electrical harness must not rub on
sharp edges.
- The electrical harness should not be
stressed at connections (see Figure below)
-
- The voltage drop between the battery and
the fan should not exceed 5% of the rated
battery voltage. This should be verified at
the pump’s maximum current draw.
Wiring or electrical harness must not rub or
make contact with a hot surface. There
should be 5" minimum clearance from the
exhaust.
- Wiring or electrical harness should be
supported at least every 18" to 20".
- To avoid possible fire or shock, do not pinch
any wiring or electrical harnesses.
-
- Incorporate Drip Loops into wiring designs
(see Figure below). The pump connectors
are environmentally sealed. However, good
wire management can help ensure a good
seal over the life of the product
- The use of Dielectric Grease such as Dow
Corning DC-4 is acceptable as long as the
connection is mated directly after grease
application to prevent dirt from being
captured by the grease
Wires pulling on connectors can
compromise the connector body seal
and possibly create a water intrusion
event
Wire routing provides a path for water to flow
down into connector
Drip loop collects water and sheds it away
from connectors

The Dual Orientation pumps cannot be mounted at any arbitrary angle (i.e. 45 deg off axis). Standard Service
pumps can use either the Vertical or Horizontal Orientations listed on the previous page.
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. An incorrect mounting angle may also result in too
much fluid being retained in the weep pocket resulting in bearing contamination and reduced service
life.

Physical Inspection
CAUTION: DO NOT RUN THE PUMP WITHOUT FLUID PRESENT. IF RUN DRY EVEN FOR A SHORT
PERIOD THE SEAL WILL BE DAMAGED.
1. Make sure the weep hole ports are not clogged with debris. If weep holes are plugged then
open them up.
Weep Hole Ports
2. While the pump is connected to the bus, remove the 6 pin plug and connect the TTL adapter
and turn the bus and heating switches "on" (to enable pump).
a. 24V power and IGN must be supplied to pump or it will not connect to the service tool.
b. Use EMPower Connect™ Service Tool to verify that the pump is on and running at
correct speed.
3. Evaluate the pump for abnormal noises during operation. This is a subjective evaluation,
vibration is not grinding; the user is looking for a noticeable bearing noise.
4. Observe the pump and area for leaking coolant. Fluid pouring out of the weep hole would
indicate a failed mechanical seal. Dampness around the weep pocket is acceptable.
NOTE: COOLANT MAY BE SEEN OUTSIDE THE EMP WP29 ELECTRIC WATER PUMP. Mechanical Seal
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.
In properly oriented pumps, the vapor will harmlessly evaporate unless the outside surfaces are
cool enough to condense the vapors, which may result in a small volume of coolant visible on the
exterior of the weep holes
There are two weep holes that vent from the same cavity. One will be capped with a solid plug,
the other with a cap with two holes. If the pump seals are leaking excessively, fluid will come
through the holes.
Acceptable Leakage
Depending on pump installation orientation, pumps may show up to 10 cc external leakage during
the first 100 hours. In the preferred orientation, about half this amount may have external leakage.
10 cc coolant will make a small puddle approximately 4 inches across on a flat surface.

EMPower Connect™ Service Tool
Monitoring operation and manual control of the pump can be accomplished using the service tool
EMPower Connect which is part of the EMP Service Suite available at no cost on our website at:
http://www.emp-corp.com/support/downloads/ . To use EMPower Connect download and install on
your PC. If the pump is being run standalone you will also need an interface cable from the 6 pin
Deutsch connector on the pump and an EMP USB/TTL converter. Both are available as a kit P/N
7500038001. If the pump is on a J1939 CAN bus EMPower Connect™ can be run using a Data Link
Adapter (DLA) to interface to the CAN bus.
