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.

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. parmesan.
Locate the pump on a firm footing to make sure the pump will not move due to vibration. Flex-coupled and Vbelt-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.

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 matches the electrical specifications of the pump.

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 the pump shaft, never check the direction of electric motor rotation without first disconnecting the flexible coupling. parmesan.

> Suction
[4 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 the 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 is 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 dipstick 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. barmesa.com

CAUTION
DO NOT OPERATE PUMP WITHOUT LIQUID IN THE PUMP BODY AS OPERATING DRY WILL RESULT IN DAMAGE TO THE SEAL.
Starting
After completion of the procedures outlined in the past sections, the pump is then ready for operation.
Start the pump by applying power to the motor or by starting the engine as outlined in the ENGINE or MOTOR INSTRUCTION MANUAL.

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

Check Valve
Disconnect the suction piping and remove the hex nuts (27), and suction flange (2). DO NOT PRY ON FLANGE but bump off with a block of wood and a hammer. Remove gasket  (31), weights (3) & (4), and screw (25), and replace if worn or damaged.
To replace, the HINGE section of gasket (31) is at the TOP and the LARGE weight is on the pump side of the gasket.

Body & Impeller
Disconnect suction and discharge piping. To expose body (5), and impeller (6) for clean out or replacement, remove hex nuts (26) and lock washers (16) then remove body (5) and gaskets (29) & (30) from bearing pedestal (1). If impeller (6) needs replacement, unscrew from shaft (10). Note the number of shims (17) & (18). The impeller has right-hand threads, so to break it loose use a block of wood against a vane and strike with a hammer. parmesan.c

Shaft Seal
Remove the body and impeller. Remove impeller shims (17), (18), and seal spring holder, spring, and rotating member of seal (14) from shaft (10). Replace if worn or damaged. If the stationary member needs replaced, remove screws (21) and pull the seal plate (8) together with the stationary from the bearing housing (1). Press stationery out of the seal plate (8).

CAUTION HANDLE SEAL PARTS WITH EXTREME CARE. DO NOT SCRATCH OR MAR LAPPED FACES.

To reassemble, lightly oil the seal the cavity in the seal plate (8) and ring of the stationary member. Replace seal plate (8) onto bearing housing (1). Lightly oil shaft (10) press stationary over the shaft and into the seal plate (8). Lightly oil shaft sleeve (11) and the inner surface of bellows of the rotating member. With lapped surface facing bearing housing, slide the rotating member onto the shaft sleeve (11) until the lapped faces are of the rotating member and stationery together. Replace the spring and spring holder and reassemble the remainder of the pump.
When impeller (6) is removed, also remove shims (17) & (18). To reassemble be sure to use a combination of impeller shims (17) & (18), and body gaskets (29) & (30) to result in an impeller-to-body clearance of approximately 0.015″.

Shaft & Bearing
Pull deflector (28) from shaft (10), remove cap screws (22), lock washers (16), and pull front bearing cap (7) with oil seal (15) and shims (19) & (20) from bearing pedestal (1). Tap on the drive end of the shaft (10) with a block of wood and a hammer, driving the shaft with bearings from the pedestal (1).

Press bearings (13) from shaft (10) and remove the oil seal (15) from the pedestal by tapping with a drift and a hammer.
Press a new oil seal (15) into the pedestal with an open end toward the bearing (see Figure 1). Press the cone and roller of the drive end bearing (13) onto shaft (10) seating it snug against the shaft shoulder, with the tapper running toward the impeller end of the shaft. Press the complete front bearing (13) onto the impeller end of shaft (10) seating it snug against the shaft shoulder with the tapper running toward the drive end of the shaft.

Place assembled shaft and bearings into pedestal (1) key end first. Press the oil seal (15) into the bearing cap (7).
Replace bearing cap (7) and oil seal (15) using the required number of shims (19) & (20) to allow for a 0.005″ shaft end play with cap screws (22) and lock washers (16). Replace deflector (28) onto shaft (10) before reassembling the remainder of the pump. barmesa.com
