exceed 2 m.
 Mount the pump on a flat, level surface and bolt it to the surface securely so as to avoid
vibration and distortion of the pump.
 At the pump stopping, there are possibility that fluid flow back from pump, due to the
liquid level differential of pump inlet and outlet. In order to prevent this reverse flow,
install a check valve on the piping.

Liquid piping
 The suction opening and the discharge opening of the pump are marked with “IN” and
“OUT” respectively. Use a pipe fitting suitable for each opening according to the fitting’s
instruction manual to ensure leak-free connection between the pump and piping.
 Hold the fitting body (attached to the pump) while tightening the fitting union nut.
Otherwise, the fitting body will be forced to turn with the union nut, which may
damage the fitting, thereby causing liquid leakage.
Note:
For installation of super type fittings, refer to the Instruction Manual for Super Type
Pillar Fitting (Manual No. 048*).
For installation of super 300 type fittings P-series, refer to the Instruction Manual for

Table 11: Tightening torque of through bolts
Pump type Tightening torque
PE– 5 MA 5.0 – 5.2 N•m
PE–10MA 8.8 – 9.2 N•m
PE–20MA 21.8 – 22.6 N•m
PE–40MA 31.4 – 32.4 N•m
PE–80MA 48.6 – 50.0 N•m
 Check the pump for normal operation. If something abnormal is found, locate and remove
the cause according to 7. Troubleshooting Guide on page 17 before starting the pump.

Periodic inspection
 Check the pump through bolts for tightness every three months. If looseness is found,
stop the pump, cool down the pump to 30°C or lower, release the air pressure to zero, and
loosen the mounting bolts in the pump base. Then remove the caps of through bolts and
retighten the bolts in a crisscross manner to the specified torque shown in Table 11.
 Check consumable parts such as bellows, check valves and O-rings at intervals of two
years or 42 million strokes, whichever is earlier. If the pump is used to deliver the
following chemicals, however, check the consumable parts at intervals of 5 million
strokes.
Highly reactive chemicals including hydrazine, fuming sulfuric acid and stripper
Checking the consumable parts needs an overhaul of the pump, and request us for pump
overhaul. For details on how to request our overhaul service, refer to 9. Overhaul Service
on page 19.
