Abstract
The present invention relates to improvements in or relating to pump installations, It has particular relevance in the field of reciprocating piston pumps, such as condensate removal pumps which are used to remove condensate from air conditioning installations. We describe a liquid pulse damping device (20) comprising a body (21) having an inlet (22) and an outlet (23) in fluid communication. Intermediate the inlet and outlet is at least one liquid flow direction changing element (24, 25). Preferably, the at least one flow direction changing element (24, 25) is in the form of an elongate element having a closed end (30, 31) and a side wall, suitably a cylindrical side wall, having at least one bore (40) formed therethrough.
