PA SERIES HORIZONTAL CHEMICAL PUMPS

pa SELF-priming PUMPS

Self-priming chemical pumps (pump above the liquid level). Available in three sizes, they meet a wide range of needs: emptying underground tanks, draining sumps or general maintenance work. Installation (above the free surface of the liquid) requires special attention: for example, the delivery pipe must run downwards towards the pump, while the suction pipe must be as short as possible and have an inclination to avoid pockets of stagnation or air bubbles. In addition, their suction capacity is altered by unsupported pipes, shut-off or non-return valves, tight radius bends, pipes with a diameter smaller than that of the suction and delivery ports.
