instructions in this
manual completely,
before installation and start-up of the pump.
It is the responsibility of the purchaser to
retain this manual for reference. Failure to
comply with the recommendations stated
in this manual will damage the pump, and
void factory warranty.
IMPORTANT
OPERATING INSTRUCTIONS
This pump has been tested prior to shipment from factory. The oil reservoir has
been partially filled at testing with air motor lubricant and should be completely filled
before operation. When reservoir is full, the pump will not require refilling for approxi-
mately 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 opera-
tion. 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 automati-
cally 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 Shell TELLUS ® T Oil 32 Premium Multigrade AW
Hydraulic Oil air motor lubricant, 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.
