INTRODUCTION OF GRACO DIAPHRAGM PUMP HUSKY 2150 MODEL

Diaphragm pump Graco Model 2150 Husky is a powerful turbine pump of this company, which can move and pump up to 568 liters per minute with a maximum working pressure of 8.4 bar. This powerful pump has a 2-inch material inlet and outlet and can transfer all kinds of fluids such as alcohols, bases, acids, edible and industrial oils, etc. Another advantage of this American Graco diaphragm pump is the maximum suction depth of 6.3 meters, and the user can use this device in various industries such as petrochemicals, factories, laboratories, etc. Also, this device has the ability to easily pump liquids with particles up to 2.4 mm without settling inside the device. Some fluids may destroy this device due to their corrosive properties, that’s why this model of diaphragm pump is available in PP (polypropylene), Alu (aluminum) and SST (stainless steel) materials. Each of these pumps is unique for transferring fluids and special materials.

Changing the Orientation of the Fluid Inlet and Outlet Ports The pump is shipped with the fluid inlet (R) and outlet (S) ports facing the same direction. See Fig. 3. To
change the orientation of the inlet and/or outlet port: 1. Remove the screws (106) holding the inlet (102)
and/or outlet (103) manifold to the covers (101). 2. Reverse the manifold and reattach. Install the
screws and torque to 120 to 150 in-lb (14 to 17 Nm). on aluminum pumps. Torque to 190–220
in–lb (22–25 Nm) on ductile iron and stainless steel pumps. See Torque Sequence, page 29.

2Fluid Pressure Relief Valve

Some systems may require installation of a pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or

hose. See Fig. 4.

Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambient heat, or when pumping from a cool to a warm
area (for example, from an underground tank). Overpressurization can also occur if the Husky pump is being used to feed fluid to a piston pump, and the intake valve of the piston pump does not close, causing fluid to back up in the outlet line.

Air valve repair service

Tools required: torque wrench

Torx (T20) or 7mm (32/9″) socket screwdriver

Narrow tail wrench selection O ring
lithium base grease

Note: Air valve repair kit 236273

(aluminum center housing) and 255061 (stainless steel center housing) are available. See page 24. The parts in
the kit are marked with a symbol, for example (4).
Use all the parts in the kit for best results.

deassembleing

1. Follow the pressure relief procedure warning on page 10

2. With a Torx (T20) or 7 mm (9/32 inch) screwdriver

Remove the socket wrench, six screws (3), air
valve cover (2) and washer (4). See Figure 6.
3. Move the valve carriage (5) to the middle position
and pull it out of the cavity. Remove valve
block (7) and o-ring (6) from carriage. Using a pair of
needle nose pliers, pull the pilot block (18) straight
up and out of the hole see Figure 7.

4. Pull out the two driving pistons (11) from the bearing (12). u-cup packs (10) from

Pistons Pull the pilot pins (16) out of
the bearing (15). Remove the circlips (17) from the
pilot pins, see Figure 8.
5. Check valve plate (8) in place. If damaged,
use a Torx screwdriver (T20) or a 7 mm (9/32 inch)
socket wrench to remove the three screws (3).
Remove the valve plate (8) and the aluminum plate

Center housing models only, remove seal (9).

See figure 9 HUSKY Graco 2150 diaphragm pump.

6. Check the bearings (12, 15) in place. See Figure 8.
The bearings are tapered and in case of failure, must
be removed from the outside, this requires the separation of the fluid part. See page 20.
7. Clean all parts of HUSKY Graco 2150 Diaphragm Pump and check for wear and damage.
Replace if needed.

Reassemble as described above

piston (11), so the lip of the pack faces the
narrow end of the pistons (see Figure 8).

6. Lubricate the u-cup packing (10) of HUSKY Graco 2150 Graco Husky Diaphragm Pump and Actuator
Piston (11). Drive pistons into

7. Grease the lower part of the pilot block (18) and

Install so that its tabs are fixed to the grooves on
the ends of the HUSKY Graco 2150 diaphragm pump pilot pins (16). See Figure 7.

8. Grease the o-ring (6) and install
it in the valve block (7) Press the block on the valve carriage
