Recommendations, Warnings & Installation

• Receiving inspection
  Upon receiving the pump, it should be inspected for damage or shortages. If damage has occurred, file a claim immediately with the company that delivered the pump. If the manual is removed from the packaging, do not lose or misplace it.

• Storage
  Any product that is stored for a period longer than six (6) months from the date of purchase should be bench-tested prior to installation. A bench test consists of, checking the impeller to assure it is free turning and a run test to assure the motor (and switch if provided) operates properly.

• Controls
  Manual models require a separate approved pump control device or panel for automatic operation. Be sure the electrical specification of the control selected properly match the electrical specifications of the pump.

• Installation Location:

  • The pump should be located as near as possible to the liquid to be pumped and in no case should the pump be more than 25 feet above the surface of the liquid supply.
  • The pump should always be as level as possible.
  • Locate the pump on a firm footing to make sure the pump will not move due to vibration.
  • Flex-coupled and V-belt-driven units should be permanently grouted onto a cement foundation.
  • The pumps should be level to provide favorable operating conditions.
  • In addition, the flexible coupling should be realigned after grouting in order to eliminate excessive wear on the coupling.
  • Allow a minimum of 18 inches in front of the pump case cover or hatch cover to permit easy removal and access to the interior of the pump.
  • On belt-driven units, allow a minimum of 10 inches at the shaft end to permit easy removal of the pedestal or rotating cartridge.

• Rotation
  All pump units rotate clockwise when looking from the driven end of the pump. The impellers are threaded on the shaft and it is necessary to slide one half of the flexible coupling back when checking rotation in order to eliminate the possibility of unscrewing the impeller and damaging the pump. NOTE: Where impellers thread on pump shaft, never check the direction of electric motor rotation without first disconnecting flexible coupling.

• Suction

  • CAUTION THIS PUMP SHOULD NOT BE OPERATED WITHOUT A STRAINER ON THE END OF THE SUCTION LINE TO PREVENT STICKS. STONES, RAGS AND OTHER FOREIGN MATTER FROM BEING DRAWN INTO THE IMPELLER. THE STRAINER SHOULD BE CLEANED REGULARLY TO ENSURE FULL FLOW.
  • It is advisable to use a suction line of the same size as the pump port size. All horizontal suction lines should slope up to the pump to avoid trapped air pockets. An adjustable stand, pipe clamp or floor flange must be installed to support the weight of the suction line. Using a smaller suction line than the pump port size can cause internal damage to the pump.

• Discharge
  Connect discharge hose or pipe to the side outlet on the discharge tee or to the discharge elbow.

• Driver
  Read the engine or motor manufacturer’s instruction book.

• Lubrication
  The only part of the pump requiring lubrication is the bearing housing. The impeller and shaft seal are lubricated by the liquid being pumped and need no other lubrication.
  The bearing housing is factory filled with 90-weight oil, for bearing lubrication. The oil level in the bearing housing should be periodically checked. This is accomplished by removing the oil dipstick and checking oil level shown on it. If oil is required, add through the dip stick hole.

• Operation
  Priming:
  Remove the priming plug(s) in the top of the pump body, and fill the pump body completely with liquid as free of solids as possible. In freezing weather, the pump should be primed with warm water, if possible, to prevent any damage that may be caused by ice films within the pump.

• CAUTION DO NOT OPERATE PUMP WITHOUT LIQUID IN PUMP BODY AS OPERATING DRY WILL RESULT IN DAMAGE TO THE SEAL.

• Starting
  After completion of procedures outlined in the past sections, the pump is then ready for operation. Start pump by applying power to motor or by starting engine as outlined in the ENGINE or MOTOR INSTRUCTION MANUAL.

• Shutdown
  Disconnect electric power or stopping engine to shut down. It is recommended to drain and flush pump if pump has been operating in freezing weather.

• Service
  Turn off and lock out power before servicing pump.

• Check Valve
  Disconnect suction piping and remove hex nuts, and suction flange. DO NOT PRY ON FLANGE but bump off with block of wood and a hammer. Remove gasket, weights, screw and replace if worn or damaged.

• Body & Impeller
  Disconnect suction and discharge piping. To expose body, and impeller for clean out or replacement, remove hex nuts and lock washers then remove body and gaskets from bearing pedestal. If impeller needs replacement, unscew from shaft. Note the quantity of shims. The impeller has right-hand threads, so to break loose use a block of wood against a vane and strike with hammer.

• Shaft Seal
  Remove body and impeller. Remove impeller shims and seal spring holder, spring and rotating member of seal from shaft. Replace if worn or damaged.
  If stationary member needs replaced, remove screws and pull seal plate together with stationary from bearing housing. Press stationary out of seal plate.

• CAUTION HANDLE SEAL PARTS WITH EXTREME CARE. DO NOT SCRATCH OR MARLAPPED FACES.

  • To reassemble, lightly oil seal cavity in seal plate and ring of stationary member. Replace seal plate onto bearing housing. Lightly oil shaft press stationary over shaft and into seal plate. Lightly oil shaft sleeve and inner surface of bellows of rotating member.
  • With lapped surface facing bearing housing, slide rotating member onto shaft sleeve until lapped faces are of rotating member and stationery together. Replace spring and spring holder and reassemble remainder of pump.
  • When impeller is removed, also remove shims. To reassemble be sure to use a combination of impeller shims, body gaskets to result in an impeller-to-body clearance of approximately 0.015″.

• Drive, Shaft & Bearings
  Contact an authorized Barmesa dealer.
