Operation and Maintenance
Check oil level prior to starting and en-
sure trouble-free water supply . Oil: Use
only 23.7 ounces (0.7 litres) of Giant oil
(p/n 01154) ISO VG 220 (e.g. Aral Degol
BG220) or SAE 90 gear oil.
Initial change after 50 operating hours and
then every 1000 operating hours or after 1
year if used less.
Caution! When operating in damp places
or with high temperature uctuations.
Should condensate (frothy oil) occur in the
gear box, oil must be changed immediately.
Maximum input pressure 145 PSI (10
bar).
Maximum suction head -4.35 PSI (-0.3
bar) (dependent on the viscosity of the
medium). Maximum input pressure 145
PSI (10 bar), maximum suction head -4.35
PSI (-0.3 bar). Make sure that suction
pulsation is su󰀩ciently dampened - water
column resonance must be avoided.
Safety Rules
Pump operation without safety valve as
well as any excess in temperature or speed
limits automatically voids the warranty . The
safety valve must be regulated in accor-
dance with the guidelines for liquid spraying
units so that the admissible operating pres-
sure can not be exceeded by more than
10%.
When the pump is in operation, the open
shaft end must be oovered up by a shaft
protector (17). The driven shaft side and
coupling (or belt guard) should have a
metal guard over all moving parts.
Before any maintenance to the pump takes
place, the pressure in discharge line and in
pump must be at zero. Close suction line.
Disconnect fuses to ensure that the driving
motor is not accidentally switched on.
Before starting the pump, make sure that
all parts on the pressure side of the unit are
vented and relled (with pressure at zero).
In order to prevent air, or an air/water-mix-
ture being absorbed and to prevent cavita-
tion occurring, the pump-NPSHR, positive
suction head and medium temperature
must be kept under control.
Cavitation and/or compression of gases
lead to uncontrollable pressure-kicks
which can ruin pump and unit parts and
also be dangerous to the operator or
anyone standing nearby.
The BP100 pump is suitable for pumping
clean water as well as for water containing
bentonite in a concentration of maximum 55
lbs. (25 kg) of bentonite diluted in 264 gal-
lons (1 cubic meter) of water.

Specications
Model BP100
Consult the factory for special requirements that must be met if the
pump is to operate beyond one or more of the limits specied above.
PULLEY INFORMATION
Pulley selection and pump speed are based on
a 1725 RPM motor and “B” section belts. When
selecting desired GPM, allow for a ±5% tolerance
on pumps output due to variations in pulleys, belts
and motors among manufacturers.
1. Select GPM required, then select appropriate
motor and pump pulley from the same line.
2. The desired pressure is achieved by selecting
the correct nozzle size that corresponds with the
pump GPM.
HORSEPOWER INFORMATION
Horsepower ratings shown are the power re-
quirements for the pump. Gas engine power
outputs must be approximately twice the pump
power requirements shown above.
We recommend that a 1.15 service factor be
specied when selecting an electric motor as the
power source. To compute specic pump horse-
power requirements, use the following formula:
(GPM X PSI) / 1450 = HP
U.S. (Metric)
Volume..................................................... 5.9 GPM................. (22.5 LPM)
Discharge Pressure ................................. 1885 PSI ................ (130 bar)
Maximum Crankshaft Speed ................................................... 750 RPM
Power Required....................................... 8.0 HP.................... (6.0 kW)
Plunger Diameter..................................... 1.02”....................... (26mm)
Stroke ...................................................... 0.79”....................... (20mm)
Crankcase Oil Capacity ........................... 24 .oz. .................. (0.7 L)
Temperature of Pumped Fluids................ 194 oF.................... (90o C)
Inlet Ports................................................................................. (2) 3/4” NPT
Discharge Ports ....................................................................... (2) 1/2” NPT
Crankshaft Mounting................................................................ Either Side
Shaft Rotation.......................................... Top of Pulley Towards Fluid End
Weight...................................................... 41.9 lbs. ................ (19 kg)
SPECIAL NOTE:
The theoretical gallons per revolution (gal/rev) is 0.0078667
To nd specic outputs at various RPM, use the formula:

16. To remove the crankshaft (18), rst remove the bearing cover plates (12). Remove the key (19).
17. With a 5 mm allen wrench remove the connecting rod screws (20A) and rear portion of connecting rod as-
semblies (20). Push the connecting rod (20) and plunger rod (22) down as far as possible into the crankcase
housing.
18. Hold the pump rear assembly with a wooden xture, or other suitable device, in order to secure it while re-
moving the crankshaft (18). Using a plastic mallet, tap the crankshaft from one side while turning it from the
other side. The turning insures that during this sequence the crankshaft does not become wedged against
the front portion of the connecting rods (20). The far side bearing (15) will remain in the crankcase (1). When
free, the crankshaft can be removed by hand. The opposite side crankshaft seal (14) will be removed by this
procedure. It is important that you turn the crankshaft (18) constantly while tapping from the opposite
end to avoid any binding. The crankshaft bearing (15) remains on the crankshaft as it is removed. If
necessary, use a bearing puller to remove the crankshaft bearing (15).
19. Remove the front portion of the connecting rods (20) and plunger base assembly (22) from the rear of the
pump by pulling straight out of the crankcase crosshead guides. Notice that the connecting rod (20) halves
are numbered or colored. Connecting rods must be positioned with their numbers or colors on the
upper left-hand side, in the same numerical sequence as when they were removed.
20. Using a dowel and a rubber mallet, tap the oil seals (26) out from the rear of crankcase (1). The area onto
which the oil seal rests should be clean and dry. Put a small drop of loc-tite on the oil seals and place into
crankcase with lips facing the rear of the pump.
21. To remove the crosshead pin (23) from the crosshead (22), the assembly should be positioned on a wooden
xture to avoid damage to crosshead. Drive out the pin on opposite side of mark located on the crosshead.
On those pumps without mark on crosshead, drive out pin by tapping on tapered side of pin.
22. To remove the bearing (15) remaining in the crankcase (1), insert small end of Giant bearing tool and tap with
a rubber mallet until bearing and seal (14) are completely removed. The bearing can only be removed from
the inside by inserting the Giant Bearing Tool through the opposite side of the crankcase. The cross-
head guide in the crankcase should be inspected for possible damage.

23. To reassemble, place the far bearing (15) in the crankcase (1) bearing housing and with the Giant Bearing
tool as a driver, tap into the crankcase using a rubber mallet.
24. Insert the far side crankshaft oil seal (14) with the Giant Bearing Tool making sure it is rmly seated and well
oiled. Always make sure that the crankshaft seal lip does not show signs of wear and that the garter spring
is rmly in place on the seal before reinserting into the pump. Replace the bearing cover (12) and o-ring (13)
and tighten securely.
25. Replace the front portion of the connecting rod (20) and plunger rod/ crosshead assembly (22) by press-tting
the crosshead pin (23). Make sure to insert the beveled edge of the crosshead pin into crosshead. If the
crosshead has a mark, install pin from marked side. The crosshead pin (23) should not extend beyond
either side of the crosshead (22) in order to prevent damage to the crosshead bore of the crankcase
(1).
26. Place each crosshead/ plunger assembly into the pump making sure that all of the parts are well oiled before
insertion into the crankcase (1). Notice that the connecting rod (20) halves are numbered or colored.
Connecting rods must be positioned with their numbers or colors on the upper left-hand side, in the
same numerical sequence as when they were removed.
27. Replace near side bearing (15) on crankshaft by using the Giant Bearing Tool and mallet to tap into place.
Take the crankshaft (18) end with the bearing (15) and insert the other end through the bearing housing and
tap with a rubber mallet until the bearing is seated.
28. When reassembling the connecting rods (20), note that the connecting rod halves are numbered or colored
and that the numbers or colors must be matched and aligned. Torque the connecting rod bolts to 310 in.-lbs.
29. Insert the near side crankshaft oil seal (14) with the Giant Bearing Tool making sure it is rmly seated and well
oiled. Replace the bearing cover (12) and o-ring (13) and tighten securely.
