Use as booster pump to circulate coolant overnight or before morning start and keep fuel tank, filter, lines, warm, using heated coolant from use of existing engine heater (block heater, oil pan heater).
We have looked for the best overall pump for circulating coolant, and believe this one gives the best quality and features for the money. MAGNETIC DRIVE. Nothing to wear out, no shaft seals to leak. 50,000 hour rated. Used by the military as a booster pump to circulate coolant to the rear of Hummers.
Variable speed! Adjust the dial on the base to get the flow rate you need.
Very low power requirement: 1.9 amps: with a good battery (Optima yellow top combination deep cycle/starting battery for example), this means the pump can be run a number of hours after the engine is shut off and use residual heat to keep a system (in-tank heater, filter, fuel lines) warm! Add our MFT timer and you can set the time period the pump runs after the ignition is turned off. For example, you turn engine off, and set timer for 5 hours, plug in block heater. The pump runs for that period only, drawing just a few amps, then shuts off. Your fuel filter, lines, and tank will be warm for a few more hours...warm enough that fuel flow will not be an issue at startup. The tank, lines and filter can be kept "ready to go".
The other advantage of adding the timer is that of course you will not have to worry about forgetting you left a pump switched on when leaving the engine off for a longer period (like when you park at the airport and run off to catch a plane!)
Or, run off an inverter, and, again, plug in the block heater for the engine, and circulate heated coolant to entire system all night, for a fast switchover to heated SVO in the morning on the coldest nights; then run the pump as a booster pump to get maximum flow to the in-tank heater while driving.
Can be operated on 12 or 24V systems. Easy to change motor out to 120 VAC if desired, you do not even have to remove the pump from the coolant lines. Let us know if you need the 120 V AC version instead of this one! We can ship that way.
Can be mounted with brass housing up, or on side. Do not mount with brass housing down. Mounting bracket is not included.
1/2" NPT fittings. Brass housing withstands high temperatures.
1 year warranty.
