Page 10: Installation
Installation Always refer to the local or national regulations and codes relating to the selection of the installation site, the water and power connections, etc. Position Pumps should be installed in a protected environment, not exposed to weather. Make sure that there are no obstructions to prevent proper motor cooling. Anchoring The pump must be secured to a solid foundation by bolts through the holes in the flange or base plate. -
Page 11: Electrical Connection
Description If it is necessary to increase the diameter of the suction pipe, place an eccentric reducer between the check valve and the flexible pipe section. Using elbows will increase the flow resistance. Wide bends will result in lesser flow resistance. 10 The piping must have a level or positive gradient to prevent the formation of air pockets. - Page 12 For VM, VMC, VMN 1, 3, 5 series For these pumps, it is advisable to open the bypass valve during start-up. The bypass valve connects the suction and discharge sides of the pump, thus making the filling procedure easier. When the operation is stable, the bypass valve can be closed.
