Installation requirements
(Continued)
Oil tank
The design of the tank is important so that air bubbles are
not drawn into the pump and on into the system. Here are
two recommended designs:
1. Air bubbles from the return oil are guided by the oil flow
up to the oil surface (venting area) via an oil pipe mount-
ed at the bottom of the tank. Another option, yet not as
reliable, is a tank with a solid baffle plate as shown in the
middle picture.
2. Eventual drainage hoses is connected close to the
bottom, as far as possible from the suction connection.
3. Large return filter corresponding to 4 x the pump flow.
4. Separate air filter, which is fitted protected from water and
dirt.
5. Suction connection close to or in the bottom of the tank
on the opposite side to the return filter.
6. The net volume of the tank should be at least 1.5 x the
pump flow and positioned so that the oil level lies above
the pump.
A traditional tank fitted with a baffle plate with holes is not
recommended as this does not deaerate the oil satisfacto-
rily.
Sunfab Oil tank
This tank is included in the Sunfab range of accessories.
It incorporates the latest advances in tank design to give
trouble-free operation.
The tank is available in two material options: stainless steel
and aluminium.
Pressure relief valves
The hydraulic system must be equipped with a pressure
relief valve for each circuit if the flow is used for different
functions.
