Description and Speciﬁcations

WARNING

CAUTION

This Self-Priming – Centrifugal Pump is designed to pump muddy water with minute quantities of suspended solids. When pumping water, the pumps are self priming on static suction lifts up to 25 feet (7.6 meters), while with liquids which foam or foam emulsions, the static suction lift is reduced to 10 feet (3 meters). A cast iron impeller with solids handling capabilities is used.

THIS PUMP IS DESIGNED TO PUMP WATER. NEVER USE THIS SELF PRIMING PUMP TO PUMP FUEL, FLAMMABLE, CORROSIVE OR COMBUSTIBLE LIQUIDS. PUMPING ABRASIVE LIQUIDS IS ALSO HAZARDOUS. IF IN DOUBT, CONSULT FACTORY FOR PROPER USE AND APPLICATION.

BEFORE USING YOU SELF-PRIMING – CENTRIFUGAL PUMP, READ AND FOLLOW THESE SAFETY PRECAUTIONS.

installations are suitable for the liquid being pumped and comply with all applicable codes and regulations.

plumbing connections to the pump body. Rigid piping may put stresses on the pump, causing damage. If rigid piping must be used, properly support it so as to eliminate stresses on the pump.

12. Do not run the pump dry. Always ﬁll the pump body

with water before starting. It is not necessary to drain the pump body after use, unless there is danger of freezing, settling of solids, or crystallization.

13. Do not subject pump to extreme conditions of acidity

or basicity. Consult factory for speciﬁc recommendations concerning chemicals and temperatures.

14. Only use original spare parts.

2. Before Starting

2.1 A suction strainer should be attached to the suction

hose or pipe. It is provided with holes or slots small enough to prevent big stones, etc., from working through and damaging the pump. Keep the strainer clean. If possible, suspend the strainer to keep it from working into the sediment. Or, A) Prepare a bed of stones on which to rest the strainer. B) Tie the strainer inside a basket or pail.

2.2 Fill the engine crankcase and air cleaner with oil as

speciﬁed in the Engine Manual.

2.3 FUEL: Regular gasoline (leaded or unleaded) which

can be mixed to the extent of 10% by volume with ethanol. DO NOT use methanol.

2.4 Fill the pump with water through the priming port

on the top of the pump. Remember the pump is selfpriming only when the pump is ﬁlled.

2.5 Make certain that all hose and pipe connections are

airtight.

IMPORTANT: An air leak in the suction line may pre-

vent priming and will reduce the capacity of the pump. Use sealant on all threaded connections.

2.6 Place the pump on level, ﬁrm foundation, putting it as

near as possible to the level of the liquid which is to be pumped, but never higher than 25 feet (7.6 meters). Keep all lines straight and as short as possible. Avoid sharp bends.

3. Operating Instructions

3.1 STARTING – See Engine Manual

3.2 PRIMING TIME – with a suction lift from 5 to 10

feet (1.5 to 3 meters), the pump should discharge liquid in less than a minute; a suction lift of 25 feet (7.6 meters), requires less than 2 minutes. To further reduce priming time the engine speed may be increased, after the engine is properly broken in. If pumping does not start within this time, shut off engine and check to ﬁnd the difﬁculty (see Troubleshooting).

3.3 CONTROL – On high suction lifts, a higher engine

speed is necessary. On shallow lifts or when there is but a little liquid to pump, save fuel and engine life by reducing the engine speed. (See Engine Manual)

3.4 CHECK VALVE – If discharge line runs vertically

more than 30 feet (9 meters), it is advisable to install a check velve in the discharge line near the pump to stop destructive water hammer when pump is shut down. If this is done, it may be necessary to vent the top of the pump so that air can be expelled during automatic re-priming. This air bleed may be accom-

plished by providing a ¼” (.5 cm) line from the top of the pump back to the liquid source. We will not assume any responsibility for damage to the pump if no check valve is used in the discharge line. Properly fueled and lubricated, your pump will run without attention.

3.5 If ﬂexible hose must be laid across a roadway, protect

it with planking. Instantaneous shutoff pressure applied when a vehicle runs over an unprotected hose will cause “hydraulic shock”, which may damage the casing or seals.

3.6 Drain the pump body whenever there is danger of freezing.

3.7 Always ﬂush out the pump at the end of operation if

the liquid being pumped may leave a solid or sticky residue in the pump. If this is not done, damage to the pump may result.

4. Troubleshooting

A) PUMP FAILS TO PRIME

1. Priming chamber empty or not sufﬁciently full.

2. Wrong direction of rotation.

3. Air leaks through the suction line joints (loose screws

or broken hoses).

4. Quick coupling gaskets broken or not well mounted.

5. Hose clamps loose or broken (tighten or replace).

6. Liquid in priming chamber overheated (ﬁll with

cold liquid).

7. Delivery line under pressure (see Operating Instructions).

8. Rotation Speed too slow (increase speed).

9. Worn or broken impeller, worn or damaged volute

(replace as required).

10. Air leaks through damaged mechanical seal (replace

the seal).

B) LOW CAPACITY

1. Suction strainer clogged (clean).

2. Suction or delivery line obstructed (remove obstruction).

3. High friction losses in the suction line (eliminate

unnecessary curves, restrictions or valves).

4. Suction lift too high (set up the pump as near as

possible to the water level).

5. Rotation speed too low (increase speed).

6. Impeller clogged (remove obstruction).
