bodily injury, death and/or property damage. Each Barmesa product is carefully inspected to insure proper performance. Closely following these instructions will eliminate potential operating problems, assuring years of trouble-free service.

Keep clear of suction and discharge openings. Do not insert fingers in pump with power connected; the rotating cutter and/or impeller can cause serious injury.

WARNING S u m p a n d s e w a g e pumps often handle materials which could cause illness or disease. Wear adequate protective clothing when working on a used pump or piping. Never enter a basin after it has been used.

DANGER “Danger” indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury.

Always wear eye protection when working on pumps. Do not wear loose clothing that may become entangled in moving parts.

DANGER Failure to permanently ground the pump, motor and controls before connecting to power can cause shock,

WARNING Installation, wiring, and junction connections must be in accordance with the National Electric Code and all applicable state and local codes. Requirements may vary depending on usage and location.

DANGER Risk of electric shock. To reduce risk of electric shock, always disconnect pump from power source before
handling any aspect of the pumping system. Lock out power and tag.
WARNING D o n o t u s e t h e s e pumps in water over 104º F. Do not exceed manufacturers recommended maximum performance, as this could cause the motor to overheat.
DANGER Do not lift, carry or hang pump by the electrical cables. Damage to the electrical cables can cause
shock, burns or death. Never handle connected power cords with wet hands. Use appropriate lifting device.

liquids and shall NOT be installed in locations classified as hazardous in accordance with the National Electrical Code (NEC) ANSI/NFPA 70 or Canadian Electric Code (CEC). The pump should never be installed in a trench, ditch, or hole with a dirt bottom. The legs will sink into the dirt and the suction will become plugged.

It is recommended that the level control float should be set to insure that the liquid in the sump never drops below the top of the motor housing or a minimum level of 10

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.

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).

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.
Oil Testing Y Drain oil into a clean, dry

Figure 2
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.

4Disassembly Impeller and Volute – Disconnect power. Remove hex nuts (24) and vertically lift motor housing and seal plate assembly from volute (31). Clean out volute (31) if necessary. 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, position squarely onto the shaft applying force to the inner race of bearing only, until bearing seats on shoulder of the shaft. In the same manner, 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 motor. Position square ring (15) on bearing housing (16) and lower housing (3) over motor and into pilot, aligning handle so that it is parallel to motor end bell reliefs.
