IMPORTANT
Read these instructions completely,
before installation and start-up. It is
the responsibility of the purchaser to
retain this manual for reference. Fail-
ure to comply with the recommenda-
tions stated in this manual will dam-
age the pump, and void factory war-
ranty.
CAUTION
This unit is pressurized internally to
line pressure so never operate without
installing all of the bolting which is
originally supplied.
PLEASE NOTE!
The photos shown in this manual are for general instruction only. YOUR SPECIFIC
MODEL MAY NOT BE SHOWN. Always refer to the parts list and exploded view drawing
for your specific model when installing, disassembling or servicing your pump.
OPERATING INSTRUCTIONS
This pump has been tested prior to shipment from factory. The oil reservoir has been
partially filled at testing with Warren Rupp Air Motor Lubricant and should be completely
filled before operation. When reservoir is full, the pump will not require refilling for
approximately 50 hours of use. (See Lubrication Instructions.)
OPERATION
Your SludgeMaster is equipped with a muffler located at side of unit. Air exhaust port
is located at top of muffler and a ¾" NPT thread is provided to extend exhaust port above
liquid being pumped. Exhaust port must be extended above liquid to prevent liquid
and foreign material from entering air motor when not in operation. This can be
done with a standard pipe, rigid plastic pipe, or hose as desired.
Connect air supply to air inlet fitting and submerge into liquid to be pumped. Unit
requires 70 CFM maximum at 80 PSI (5.51 bar) air pressure. Operation at pressures in
excess of 120 PSI (8.27 bar) is not recommended.
When handling liquid with large stones or similar solid objects, it is desirable to run unit
at full speed. This provides greater inertia for handling heavy foreign objects without
stoppage due to lodging between impeller and pump casing.
Should a foreign object lodge and prevent pump from rotating, insert a rod or bar
through hole provided at bottom of strainer into impeller vanes and bump impeller
backwards (clockwise facing strainer end) until free. Strainer can be removed when
necessary; however, this normally will not be required.
LUBRICATION
The only regular servicing required is maintaining oil reservoir which is just as
important on this unit for proper lubrication as the oil supply is for an engine. A one
quart capacity oil reservoir is provided for bearing and shaft seal lubrication and provides
oil for automatic air motor lubricator. Five drops of oil per minute is automatically
dispensed into air stream for continuous air motor lubrication and to prevent rust formation
due to moisture which is present in any air supply. Check and refill reservoir to oil fill plug
level regularly with WARREN RUPP AIR MOTOR LUBRICANT, STANDARD OIL OF
OHIO “INDUSTRON 44,” or an equivalent lightweight oil with rust inhibitor. The
automatic oiler will consume approximately 1 pint (473 cc) of oil in 50 hours of operation.
Oil reservoir should be completely drained and refilled after approximately 100 hours
operation to remove accumulated moisture.
It is beneficial to pour a little oil into air inlet connection and run for a few minutes before
storing for long periods.
This unit is not harmed by running without liquid.
DISASSEMBLY
Remove upper row of six bolts and lift off air motor and upper housing assembly. Filter
element and filter housing are now exposed and can be removed. Lower half of jaw type
coupling is threaded on pump shaft and is removed by inserting drift pin through hole
in shaft to prevent rotation while turning coupling counterclockwise with pipe wrench.
DO NOT USE JAWS OF COUPLING TO LOOSEN AS THEY CAN BE BROKEN.
Remove spacer (item 25 on Repair Parts List) from shaft and remove governor
housing assembly by lifting with screwdriver from each side. This is done by inserting
screwdriver under male connectors (see Figure 1) and prying down on intermediate
housing. Intermediate housing can now be removed by removing lower row of six bolts.
