Davies : B1 Series

B1 Series


The B series is a single cylinder double-acting piston pump especially adapted for open or pressure tank service. The enclosed type of crankcase is designed to meet a demand for a pump which has a minimum of exposed working parts, thereby securing maximum safety of operation as well as good lubrication. The pump is suitable where the vertical distance to the lowest water level does not exceed 7.6 metres (25 feet).

  • The gland should be checked periodically and tightened if necessary. Water should drip from the gland and if over tightened will increase wear on gland packing and plunger rod through lack of lubrication.
  • Check oil level regularly and change oil at least every 6 months. Belt tension should be checked one month after installation and six monthly thereafter.
  • We would recommend an annual service – although this can depend on the water quality and duty of the pump. McQuinn Pumps have engineers available to conduct annual servicing either on site or at the Service Centre.
