Page 8: Positioning The Pump
BJM Pumps, LLC at 860-399-5937. As a general rule, LWA Series top discharge pumps can pump down to a level above the suction screen. Pumping lower than screen will permit air to enter the pump and cavitate, lose prime or become air bound. -
Page 9: Pump Rotation
PUMP ROTATION Two ways to check the correct pump rotation: 1. By looking at the impeller; the rotation of the impeller should be counter clockwise as shown in the picture below. 2. By looking from the top of the pump. Since the impeller cannot be seen, the best way to check the rotation is to check the kick back motion of the pump when the pump just starts. -
Page 10: Pump Operation
PUMP OPERATION This pump is designed to handle dirty water that contains some solids. It is not designed to pump volatile or flammable liquids. Do not attempt to pump any liquids which may damage the pump or endanger personnel as a result of pump failure. -
