2. Make sure pump and trailer are level and trailer wheels are
blocked to prevent movement during operation.
Frame Mounted Pump
1. Pump frame must be supported on a level firm surface.
Anchoring pump frame to support surface is required to
prevent movement or tipping during operation. Mounting
holes are provided on bottom flange of frame side rails. Allow
sufficient clearance around pump frame to perform routine
maintenance.
All Installations:
1. Suction line should be as short and direct as possible, have a
constant slope up to the pump’s suction port, and line
diameter must match suction port diameter. Use only
reinforced non-collapsible hose on pump suction.
2. Check condition of suction hose gaskets before installation.
Weak, worn, leaking gaskets will allow an air leak at suction
connection. If suction connection leaks air, the pump will not
prime.
3. Supports must be used to carry the weight of the suction and
discharge lines. The pump should not be used to support the
entire weight of the suction and discharge lines.
Damage/breakage of pump ports may occur if lines are not
supported.
4. If a check valve or collapsible hose is used on discharge, a
means of venting air from the pump discharge manifold is
required during the priming cycle. If air cannot escape from
casing, the pump will not prime.
Lifting Bail
Pump frame is equipped with a lifting bail.
Lifting bail provides a convenient lifting point if positioning pump with a
crane or similar equipment is necessary. Bail and lifting bolt assembly
will support only the weight of frame/trailer, pump and driver.
Periodically re-torque lifting bolt assembly to 100 ft. lbs.
Remove suction and discharge lines and drain all liquid from pump
before lifting.
Lift pump assembly and trailer only. Do not load piping, hoses or
other equipment on trailer during lifting.
OPERATION
Starting Unit
1. Fill engine with oil according to engine manufacturer’s
specifications listed in engine manual supplied.
2. Fill fuel tank with appropriate fuel for engine. Do not fill tank to
the top allow at least an inch of airspace.
3. Fill pump casing with water through discharge manifold
priming port. Casing must be full of water or pump will not
prime.
Do not run pump dry as permanent damage to the mechanical seal
will result.
4. Start the engine, following instructions in engine manual.
5. Run engine at full throttle during priming cycle. Tachometer
should indicate 3500 rpm or greater.
6. After pump has primed and is producing full flow, engine
speed should be regulated to produce desired pump
performance level. Under high lift and/or low discharge head
conditions, engine speed should be decreased to retard
cavitation. This will extend pump, seal, and engine service
life.
7. Yanmar diesel engine: Maximum operating speed, after full
prime, is 3200 rpm.
Do not operate pump unattended. Shaft seal damage will occur if
prime is lost or if flow is insufficient to keep the shaft seal cool.
Refueling Tank
1. Allow unit to cool before adding fuel to tank.
2. Remove tank cap.
3. Add fuel through fill neck. Watch fuel level gauge during
filling and stop adding fuel when the gauge indicates full. Do
not overfill tank, allow an inch or two of airspace from fuel
level to top of tank.
4. Install tank cap. Rotate clockwise until it hits internal stop
indicating that it is sealed.
Pump End Drain
Pump end is equipped with an NPT drain port. The port is located on
the pump adapter plate (Ref. No. C28) at the 6 o’clock position. The
elbow (Ref. No. C30) is installed in the port to direct the liquid down
through frame. The indented hex pipe plug (Ref. No. C31) is installed
in elbow. Use a 9/16" L-hex wrench to remove plug. A ball valve and
length of pipe or hose (not supplied) may be installed to direct the
drain liquid away from the pump.
ALWAYS DRAIN LIQUID:
1. After pumping operation is complete if freezing
temperatures may be experienced.
2. Before transporting pump.
3. Before lifting pump.
Seal Wash Ports
These units are equipped with provisions for the addition of a seal
wash hose. To extend seal life or when pumping water containing
abrasive sediment or when a buildup of material on the shaft seal is
encountered, a seal wash may increase seal life. The pump adapter
plate is equipped with two 1/8" NPT tapped ports; one at the (high
pressure volute discharge) 10 o’clock position on adapter face and
one on top of the locating boss (low pressure seal cavity).
NOTE: Fittings and hose must be compatible with liquid pumped,
liquid temperature, and rated for maximum discharge pressure in the
installation.
NOTE: Addition of seal wash hose may affect priming performance.
After installing seal wash hose monitor length of time required to reach
full prime.
Standard Installation:
Remove 1/8" NPT plugs (Ref. No. C29). Install appropriate fittings and
hose between the two ports.
Abrasive Installation:
Remove 1/8" NPT plugs. Install appropriate fittings and hose between
the two ports. The installation of an in-line abrasives separator is
recommended. Contact appropriate manufacturer for details.
Clean Water Injection Installation:
Remove 1/8" NPT pipe plug from low pressure port. Connect external
clean water source line to low pressure port of adapter with
appropriate hose and fitting. Incoming pressure must be at least 10 psi
greater than seal cavity pressure. A check valve is recommended to
prevent back flow.
Transport Trailer
Pump supplied with trailer gear is for off road use only as shipped.
Trailer registration for use on public roads is the responsibility of the
owner. A Manufacturer’s Certificate of Origin listing the Vehicle
Identification Number (VIN) is included with the trailer. Trailer
registration requirements are regulated by each state and local
government. Contact your State Department of Motor Vehicles or
Department of Transportation for information and guidance on
licensing or titling the trailer/pump for towing on public roads in your
state.
