Congratulations on your purchase of the Davies, Craig Electric Booster Pump (EBP®) The EBP® is a compact, versatile, and suitable for a large range of applications. The EBP ® is designed for use alongside an EWP® (Electric Water Pump) or a conventional
mechanical water pump to enhance cooling performance. These high-performance brushless, magnetically driven EBP® are state-of-the-art technology offering lowcurrent draw, high flow capacity and long life, ideal for:

• Booster for car heater and LPG systems
• Solar and marine
• Water-cooled motorcycle
• Turbo/Supercharger water to air intercooler
• Caravans and motor homes
• Household irrigation/fishponds & tanks

EBP® Hose Sizing Guide

• The inlet and outlet of the EBP® suits 19mm (3/4”) internal diameter hose.

• For Hoses with an internal diameter smaller than 19mm (3/4”), the 12mm to 19mm plastic Stepped Adapter (#19020) and Adapter hose (#19510), may be used to configure a diameter that best suits your hose.
  NOTE: Parts #19020 & #19510 supplied with #9050 only, otherwise can be purchased separately.

• For Hoses with an internal diameter larger than 19mm (3/4”), an appropriate reducer fitting may be required.

EBP Orientation
NOTE: The EBP has built in Dry run protection When activated, the pump will run slowly until the pump is  completely free of air.
When installing the EBP ensure the inlet of the EBP is positioned horizontally, vertically up or on an upward angle.
NOTE: When the Inlet is pointed down this can lead to air locks within the pump.
For the best results, position the outlet at the highest point to aid in bleeding the pump.
Universal EBP® Installation

• Select a suitable installation location for the EBP®.
  • For the best results, the EBP® should be located low in the system and close to the outlet of the radiator, intercooler, or tank.
• Cut the hose and place hose clamps (Provided with #9050) over the hose ends.
• Identify the coolant circulation direction and install the EBP® such that coolant circulation direction remains unchanged.
• Tighten the Hose Clamps, fill the system with coolant and bleed all air from the system.

Auxiliary Pump for Water Cooled Engines

• Leaving the mechanical water pump in place, install the EBP ® into the bottom radiator hose.
• If applicable, remove the thermostat and drill two approx. 3mm (1/8″) holes in the thermostat plate to allow some coolant circulation. Re-install ensuring that the thermostat housing is clean, and a new gasket is used if required.
• For the best results wire the EBP® to be controlled by a Thermatic® Switch
  • Davies, Craig offers a full range of Thermatic® Switches available in both Mechanical (#0401, #0404 & #0400) and Digital Thermatic® Switches (#0444, #0445 & #0500).

Primary Pump for Water Cool ed Engines

• Remove the mechanical water pump and remove the impeller from the mechanical pump shaft. Retain the mechanical water pump pulley and use it as an idler to avoid re-routing the drive belt.
• Re-install the disengaged water pump ensuring that all gasket surfaces are clean, and the new gaskets are properly fitted to prevent leaks.
• Remove the Thermostat and block or re-route any bypass passages.
  • For small or low power engines typically found in motorcycles, go karts and small machinery it is best to re-route the Thermostat bypass to the EBP inlet. In this case you will need to retain the factory Thermostat.
• Install the EBP® into the bottom radiator hose.
  • If running the pump continuously and the bypass has not been re-routed remove the thermostat and drill two approx. 3mm (1/8″) holes in the thermostat plate to allow some coolant circulation. Reinstall ensuring that the thermostat housing is clean, and a new gasket is used if required.

EBP® Wiring
It is recommended that a relay (not supplied) is used to supply power to the EBP®.

You may use a manual or thermal switch on PIN 86 (ignition wire) to allow for added control over your EBP®.Wire colours are based on Davies, Craig’s standard fan wiring harness.
Wiring for Control by Thermatic® switch
Wiring for Control by Thermatic® switch Davies, Craig offers a full range of Thermatic® Switches available in both Mechanical (#0401, #0404 & #0400) and Digital Thermatic? Switches (#0444, #0445 & #0500).

• Wire the EBP® as directed by the wiring instructions provided with the Thermatic® Switch.
• All Davies, Craig Thermatic® Switches are ON/OFF.
• Toallow the EBP* to run on after hot engine shutdown, wire the Switch directly to the battery.

Replacing Existing EBP15 (#9001 or #9002)

• Replace your old EBP15 with your new EBP*.
• If required mount the EBP® using attached bracket.
• To reuse the existing EBP® 15 wiring harness you will require the EBP15 plug Adapter #19513 available separately.

Replacing Existing EBP25 (PART #9005 OR #9105)

• Replace your old EBP®25 with your new EBP®25 (#9025).
• If required mount the EBP®25 using attached bracket.
• To reuse the existing wiring EBP® 25 wiring harness you will require the EBP® 25 plug Adapter #19520 available separately.

IN ALL CASES ONCE EBP® INSTALLATION AND WIRING IS COMPLETE

• Road test the vehicle and allow the engine to reach normal operating temperature.
• Check coolant level again once engine has cooled sufficiently. Top up if required.

WARNINGS

• Do not operate your EBP® dry as damage may occur, and your warranty will be jeopardised.
• Avoid mounting your EBP® close to high heat sources like Exhaust manifolds.
• The EBP® is not recommended for use with waterless coolant.
• The EBP® is not rated for submersible use.
• Do not use ‘stop leak’ or similar leak or crack repair additives as pump damage may occur and your warranty will be jeopardised.
• The EBP® must always be completely full of coolant to achieve the life and performance expectations of your EBP®.
• DO NOT ATTEMPT to tamper with the EBP® including loosening or removing any bolts/screws as this will void any warranty. If you suspect there is a fault or defective product please contact Davies, Craig.
