6. Check O-rings (32) for deformation and wear.
Replace as needed. Install the O-rings.
REMOTE PRESSURE (Code 7), AND LOAD
SENSING CONTROL (Code 19) ASSEMBLY
See Figure 16
1. For initial assembly, follow steps 1 through 5 of the
Standard Pressure Compensator Assembly listed
above. For Load Sensing Control (Code 19) only,
install the pin (28-24) into the spool.
2. To install the seat (28-15), insert the open end into
the bore, and press into place. Install plug (28-20)
and tighten.
3. Fit the washer (28-23) and spring (28-7) onto the
adjusting screw (28-18). Fit the cone (28-16) into the
spring, and assemble into the body.
4. Set the adjusting screw to the measurement taken
at disassembly, and lock into place with nut (28-12).
Cover with acorn nut (28-22).
5. Install the O-rings (32). Assemble the compensator
to the pump cover.
HORSEPOWER LIMITING CONTROL (Code 26)
ASSEMBLY
See Figure 17
1. For initial assembly, follow steps 1 through 5 of the
Standard Pressure Compensator Assembly listed
above.
2. To install the seat (26-15), insert the open end into
the bore, and press into place. Install plug (26-20)
and tighten.
3. Fit the washer (26-23) and spring (26-7) onto the
adjusting screw (26-18). Fit the cone (26-16) into the
spring, and assemble into the body.
4. Set the adjusting screw to the measurement taken
at disassembly, and lock into place with nut (26-12).
Cover with acorn nut (26-22).
5. Place the ball (26-17) into the body, atop the
orifice.
6. Insert the pin (26-24) into the fitting assembly (26-
27), and tighten in the valve body.
7. Install O-ring (26-21) onto the fitting (26-29) and
screw into the compensator.
8. Install the O-rings (32). Assemble the compensator
to the pump cover.
TEST PROCEDURES AND SPECIFICATIONS
Pump Performance Test
1. With the operating speed at 1750 ± 35 rpm, record
delivery flow rate, drain flow rate, and fluid
temperature at minimum outlet pressure and
maximum rated continuous pressure.
Series Max. Rated Continuous Pressure
HPV-6 3500 PSI (241 bar)
HPV-10 3500 PSI (241 bar)
HPV-15 3500 PSI (241 bar)
HPV-20 3500 PSI (241 bar)
HPV-29 3000 PSI (207 bar)
2. Rate of flow at minimum outlet pressure, and
maximum rated continuous pressure should fall within
the following range:
Flow Rate At: GPM (lpm)
At Minimum At Rated
Series Outlet Continuous
Pressure Pressure
HPV-6 6.0-7.1 (22.7-26.9) 5.9 Min. (22.3)
HPV-10 9.5-10.3 (36.0-39.0) 8.7 Min. (32.9)
HPV-15 15.0-16.6 (56.8-62.8) 14.4 Min. (54.5)
HPV-20 20.0-21.4 (75.7-81.0) 18.6 Min. (70.4)
HPV-29 28.0-30.4 (106.0-115.1) 26.6 Min. (100.7)
3. Case Drain flow at maximum rated continuous
pressure and zero flow is as follows:
Series Case Drain Flow at Zero Flow
HPV-6 .93 GPM (3.5 lpm) Max.
HPV-10 .98 GPM (3.7 lpm) Max.
HPV-15 1.06 GPM (4.0 lpm) Max.
HPV-20 1.60 GPM (6.1 lpm) Max.
HPV-29 1.90 GPM (7.2 lpm) Max.
Pressure Compensator Test
Control Option Adjustment Procedures - Standard
Compensator
1. With a pump running at deadhead (no-flow), adjust
the compensator pressure to 3500 ± 35 PSI (241 ±
2.5 bar).
2. The following flow rates should be achieved:
Flow Rate, GPM (lpm)
Series Pressure, PSI (bar) Flow, GPM (LPM)
HPV-6 3325 (229.3) 5.9 (22.3) Min.
HPV-10 3325 (229.3) 8.7 (32.9) Min.
HPV-15 3325 (229.3) 14.4 (54.5) Min.
HPV-20 3325 (229.3) 18.6 (70.4) Min.
HPV-29 2850 (196.5) 26.6 (100.7) Min.
3. The pump shall return to a stable condition, with no
loss of conttrol, within one (1) second after being
cycled from full flow to zero flow.
4. Cycle the pump from zero flow to full flow to zero
flow. The zero pressures shall not vary more than
±30 psi (2 bar).
