Jabsco 11870-0005 Electro-Magnetic Clutch Pump, 12 VDC, 2-A Pulley, 1-1/4 in NPT
The Jabsco 11870-0005 is a bronze electro-magnetic clutch pump with a 12 VDC clutch, a 2-A pulley with two A-section belt grooves and 1-1/4 in NPT ports. The pump is belt driven from the engine, and the clutch lets it be switched on and off remotely from the helm or a control panel, so it only turns when water is needed. The pump end is bronze with a nitrile flexible impeller and a carbon/ceramic mechanical shaft seal. It is rated for a maximum flow of 62 GPM, self-primes from about 7.8 ft when dry and will lift up to 22 ft when wet.
Clutch pumps are the standard choice for engine driven washdown, fire, bilge and bait well service on work boats and sportfishing boats, because they deliver high flow without a large electric motor and without running all the time. Make sure all suction connections are airtight so the pump can self-prime, and never engage the clutch with the intake seacock closed, since the impeller depends on the liquid for lubrication.

Frequently Asked Questions
Q: Why a clutch rather than an electric pump?
The engine supplies the power, so the pump can move a lot of water without a large electric motor, and the clutch stops it when it is not needed.
Q: What wears first?
The impeller, followed by the shaft seal. Keep an impeller kit aboard.
Q: How do I protect it from running dry?
Keep the intake clear, avoid engaging it with the seacock closed, and consider an optional vacuum switch.
Q: Can the clutch be run off a different voltage?
No. The clutch coil is wound for 12 VDC. Match the pump to the vessel electrical system.
