barmesapumps 4Controls 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.

not be modified in any way except for shortening to a specific application.

4Submergence The pump should always be operated in the submerged condition. The minimum sump liquid level should never be less than above the pump’s volute (See Figure 1).
Pumps are most commonly installed in simplex or duplex stations or basins with a slide rail system (Barmesa SRC), which allows the pump(s) to be installed or removed without requiring personnel to enter the station, or resting on the basin floor.

4Discharge Piping
Discharge piping should be as short as possible and sized no smaller than the
pump discharge. Do not reduce the discharge pipe size below that which is
provided on the pump. Both a check valve and a shut-off valve are recommended
for each pump. The check valve is used to prevent backflow into the sump. The
shut-off valve is used to manually stop system low during pump servicing.
Always rely upon a Certified Electrician for installation.
Overload Protection: Single Phase – The stator in-winding overload protector
used is referred to as an inherent overheating protector and operates on the
combined effect of temperature and current. This means that the overload
protector will trip out and shut the pump off if the windings become too hot,
or the load current passing through them becomes too high.

With a flashlight, visually inspect the oil in the motor housing (3) to make sure it is clean and clear, light amber in color and free from suspended particles. Milky white oil indicates the presence of water. Oil level should be just above the motor when pump is in vertical position.
Oil Replacement – Set unit upright and refill with new cooling oil as per table. Fill to just above motor as an air space must remain in the top of the housing to compensate for oil expansion. Reassemble the o-ring (5) and conduit box (4) to motor housing (3). Apply thread locking compound to cap screws (6) and place into holes and torque to 15 ft/lbs.
Seal Chamber – Drain oil from seal chamber by placing pump on its side with
pipe plug (18) downward and remove pipe plug (18). If the oil is found to
contain considerable water or other contamination, the shaft seal (19) should
be inspected and replaced if required.

Pressure builds up extremely fast, increase pressure by “TAPPING” air nozzle.
Too much pressure will damage seal. DO NOT exceed 10 PSI in housing and 20-25
PSI in seal chamber.
Pressure Test Motor Housing – Oil should be at normal level. Remove pressure
valve (10) from motor housing (3). Apply pipe sealant to pressure gauge
assembly and tighten into hole (See Figure 2). Pressurize motor housing to 10
PSI.
DO NOT overfill oil. Overfilling of housing with oil can create excessive and
dangerous hydraulic pressure which can destroy the pump and create a hazard.
Overfilling oil voids warranty.
Oil Replacement: Seal Chamber – Refill chamber completely full with new
cooling oil or reuse the uncontaminated oil.

Inspect gasket (30) and replace if cut or damaged. Clean and examine impeller (27), for pitting or wear and replace if required. To remove impeller (27), remove cap screw (29) and washer (28). With a wheel puller, pull impeller straight of shaft and remove square key (13).
Motor and Bearings – Remove volute, impeller, seal plate and seal as previously stated and drain oil from motor housing (3). Position unit upright, using blocks to avoid resting unit on shaft. Remove cap screws (6) o-ring (5) and conduit box assembly (4) from motor housing (3). Note connections and then remove cable lead wires from motor lead wires and moisture and temperature sensor wires from control cable by removing connectors. Remove cap screws (12) and vertically lift the motor housing (3) from bearing housing (16).
Apply adhesive compound to the shaft and press bearing (14) onto shaft,

assemble upper bearing (2) to shaft.
Motor – Slide rotor with bearing (14) into bearing housing (16) until bearing
seats on the bottom. Position motor housing and stator into pilot, install
wave washers in upper end bell.
Moisture Probes – Drain oil from seal chamber, if not already done. Remove cap screws (9) and lifting handle (8). Set unit upside down on blocks to avoid damaging cables. Remove socket head cap screws (22)
Replace square ring (15) if damaged or cut. Remove the upper motor bolts and lift upper end bell from motor (1). Remove wave washer. Remove upper bearing (2) with a wheel puller if damaged or worn.

Diaphragm – with seal plate (20) removed, examine diaphragm (21) for ruptures
or cracks. Replace diaphragm by removing cap screws (41) and plate (40). Clean
vent holes in seal plate (20).
Vertically lift stator (1) from rotor/shaft. Inspect windings for shorts and resistance. Test the temperature sensors by checking for continuity between the black and white wires. If defective contact factory or motor service station. Pull motor rotor/shaft with bearing (14) from bearing housing (16). Remove bearing (14) with a wheel puller if worn or damaged. If rotor or stator windings are defective, replace the complete motor.
Position upper motor end bell aligning holes and thread cap screws into
bearing housing (16) and torque to 16 ft/lbs. Place all motor leads above the
