Trouble 

Causes 

Processing Method 

Unusual 
sounds 
make. 

Motor rotation direction is reverse. 

Do the connection again to correct the 
rotation direction. 

The oil is not supplied by the 
specified volume. 

Control the oil level. 
Supply the oil by the specified volume. 
Conduct the overhaul. 
(Replacement of the Pump part) 

Foreign matter has entered the 
Pump. 

Conduct the overhaul. 
(Clean the Pump to eliminate foreign 
matter) 

The oil is not circulating. 
a. Oil pit of the Cover or the like is 

clogged. 

b. Oil distributor valve has a trouble. 
 

Conduct the overhaul. 
a. Clean the oil pit. 
 
b. Check and repair the Oil distributor 

valve. 

Vanes are not moving. 

Conduct the overhaul. 
Wash out substances stuck to the vane. 

Components inside the Pump have 
burnt out. 

Conduct the overhaul. 

Belt cover screw is loose. 

Tighten the screw. 

Rattling sounds on starting or 
stopping the machine. 

There is no particular problem as it’s a 
phenomenon caused by vanes that 
temporarily make irregular motions. 

The tension of the belt is loose. 

Replace and Re-tension the belt 

Abnormal 
heating 

Keeping continuous operation under 
high suction pressure. 

Pump surface temperature would rise up 
around 100

  on continuous operation 

under high suction pressure. 

The oil is not supplied by the 
specified volume. 

Control the oil level. 
Supply the oil by the specified volume. 

Oil is dirty. 

Replace with new oil. 
Conduct the overhaul. 
  (Inside cleaning) 

Suction gas is hot. 

Install a cooling device such as the 

as 

cooler on the suction side. 

Area around the Pump is enclosed. 

Make the ventilation available. 

High temperature. 

Please use it in environment with the air 
conditioning 

There is a leak in the pipe connecting 
with the Pump. 

Use a Leak detector or the like to find out 
the leak position and stop it. 

The oil is not circulating. 
a. Oil pit of the Cover or the like is
