The pressure of each pump can be independently adjusted. 

 Remote c ontrol or high-low two-pressure control is possible.

Instructions Alignment of shaft1. Employ a flexible coupling whenever possible, 

and avoid any stress from bending or thrust. 

 Maximum permissible misalignment is less than 0.1 mm (.004 inches) TIR 

 according to the type of hydraulic fluids to be used. For details, 

and one unloading and check valve incorporated within a common housing.  

These pumps are widely used as a source of hydraulic power.  

They combine stable performance and robust c onstruction with a wide range of delivery rates.  

Two single pumps, driven by  a common shaft, have two discharge ports 

the specifications of the pumps such as maximum pump speed may be changed

Fluid viscosity and temperature2. Use the hydraulic fluids which satisfy the recommended

 viscosity and oil temperature given in the Table 2 below. However,

 p lease note that if any of the pumps listed in the Table 3 is started at low speed, 

so that the output flow can be sup-plied t o separate circuits.

please refer to the specifications o f the pump concerned.

 Set suction pressures, at the pump inlet, at the values shown in the table  below. 

 (model No. ST1004-∗-10∗, catalogue No. Pub. EC-3001.), or discharge air 

by slightly slackening the connection on the discharge side.  

At starting, operate the pump i ntermittently as far as possible with no load.  

For fluid viscosity at starting, see the item of "Hydraulic Fluids". 

Fluid viscosity and temperature Maximum viscosity for low start-up speed (Table 2) (Table 3)

Any hydraulic fluid listed in the table 1 below can be used. However , 

 In addition, use suction pipes having the sizes shown in the dimensional drawings. 

 If the pump is installed above the tank level, set the suction port more

 than 1.0 m (3.3 ft.) below from the oil level {or 0.8 m (2.6 ft.) if a phosphate ester fluid i s used}.

Precautions at starting3. At an initial operation or at an operation after a long rest, 

the pump may have difficulty in sucking up the fluid.  In such cases, 

an air bleed valve should be installed beforehand on the discharge side

the maximum fluid viscosity is limited.

Control of contamination3. Contamination of hydraulic fluids results in pump failures

 and reduced pump lives.  Carry out sufficient contamination control for hydraulic 

fluids and keep contamination level within NAS class 12.  Also, use a 100 μm (150-mesh) 

tank filter on the suction side and install it more than 50 mm (2 in.) away from the tank bottom. 

and maximum permissible misangular is less t han 0.2°. Suction pressure2.

Consists of a double pump with either two relief valves, or one relief
