2.2 - Diaphragm Pump Operation and
Maintenance (9910 D30)
Proper Maintenance and Operation for Reducer, 9910 D30
Pump and Control Valve
1. When changing oil in the Reducer, remove the drain plug
(A) located on the bottom of the Reducer. (refer to Fig. 1)
After the oil has completely drained, replace drain plug(A)
and tighten. To fill, remove side level plug (B) and vent
plug (C). (refer to Fig. 1) Fill until the gear lube is no higher
than the mark on the dipstick. After proper oil level has
been obtained replace plugs.
USE 90W GEAR LUBE TO FILL GEAR CASE
2. Check oil level in pump daily. Be sure oil is halfway up
to the clear oil sight tube (D). If it is not, fill to the correct
level using a high-grade, non-detergent, SAE 30 weight
oil. This will help prolong the pump life. (refer to Fig. 2)
3. Check the charge pressure (E) on the pulsation dampener
before starting the pump. The pressure is checked with a
standard automotive air gauge. The pressure should be at
approximately 20% of the maximum operating pressure.
(refer to Fig. 3)
4. On the pump you can adjust the pressure by clamping the
relief valve adjustment lever (F) down. With the bale hook
in the number one position the pressure is about 100 psi;
number two is about 250 psi; number three is about 450
psi; number four is about 550 psi. These pressures can
be adjusted by using the fine adjustment knob (G) located
on top of the relief valve spring. The fine adjustment knob
can be rotated when the relief valve lever is in the up
position. (refer to Fig. 3)
