VM Series Stainless Steel Vertical Multistage Pumps Installation and Operating Instructions 60Hz These Instructions must be delivered with the pump to the operator. WARNING: Failure to follow these instructions and comply with all applicable codes may cause serious bodily injury and/or property damage.
General Safety Specifications Symbols used in the manual Applications Pumps for clear liquids, free of abrasives in residential, agricultural, industrial, and other applications. Operating Conditions • Temperate range: • Ambient temperature: • Suction head: Read this data sheet carefully before installing and starting your pump. Pay special attention to the points concerning the safety of the equipment.
Two standard cases for pump installations: 1. Pump in suction lift situation. 2. Pump installed with positive inlet. Motor specifications are typical and should be confirmed at time of order. Assembly for pumps supplied without motors fitted Some Davey VM series multistage pumps require special size motor bearings built into the motor which may not allow the use of standard flange mounted motors. Suction Lift: Pumps operate more efficiently with positive suction.
Dry-running protection To avoid accidental loss of prime of the pump, we recommend protecting it with a suitable device. Refer to the motor data plate for its electrical characteristics (frequency, voltage, nominal current). The three-phase and single phase dual voltage motors must be protected by a circuit-breaker or magnetic contactor with overload set to the current marked on the motor data plate. Provide a fused disconnecting or isolating switch, in compliance with local standards.
