FILL SYSTEM WITH WATER FIRST AND CHECK FOR LEAKS – REPLACE HOSES WHEN WORN OR CRACKED.
- Max flow: 375 gpm
- Max pressure: 45 psi
- Required HP: 10 HP
- Port size: 3” FPT
- Materials: Polypropylene, Viton®O-rings,
316 stainless bolts and shaft
-Optional screw-in M300 flange adapter is P/N: 116431-01
- The standard pump is configured for gas engine use. For electric motor fitment, you must order a “-E”
pump for use on a JBC 10hp motor (see page 4).
- A shaft locating tool is used to hold the shaft during installation on the engine/motor.
This must be removed before operating the pump.
- Note that any plumbing must be supported so that its weight does not hang off of the pump – this will void
the warranty.
- If you have the -FLG version of the pump with M300 flange fittings included, the fitting threads must have
sealant applied before assembly to the pump.
- The inlet configuration of the pump may be changed by removing the 6 locknuts holding the inlet on. The
inlet check valve flap may also be removed in the high configuration.Using the pump in the high inlet
condition allows the outlet hose to drain when the pump is shut off, which is beneficial to some users.
Tighten all housing fasteners to 5 ft-lbs.
- After use flush the pump with a solution that will neutralize the fluid you have been pumping, and then
drain.Do not use water to flush acids – resulting damage not warrantied.
- The seal reservoir may be inspected by opening the fill plug. The fluid level should be approximately ½”
below the opening. If the fluid is dirty, drain by tilting the pump upside down or pull it out with a vacuum,
then replace with PREMIXED antifreeze. If the fluid is cloudy, the impeller side seal may be leaking.
