Abstract: The invention relates to an improved reciprocating pump providing oil for low pressure, self-contained oil-filled cables. It is particularly important to have a gas tight system in such a pumping plant since the oil in the storage tank (6) has to be kept under vacuum at all times to keep the oil in a gas-free condition. The air or gas driven oil pump (8) has two piston rod seals (9,10). The area between the two seals is provided with an inlet (11) and outlet opening (12) through which oil can be flushed from the high pressure side of the pump (8) to the top of a storage tank (6).
