Barmesa BSP5CU Self-Priming Frame Mounted Pump

IMPORTANT! – Read all instructions in this manual before operating or servicing a pump.

General Safety Information

Before installation, read the following instructions carefully. Failure to follow instruction and safety information could cause serious 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.

• DANGER “Danger” indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury.
• WARNING “Warning” indicates an imminenty hazardous situation which, if not avoided, MAY result in death or serious injury.
• 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.
• 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.
• Always wear eye protection when working on pumps. Do not wear loose clothing that may become entangled in moving parts.
• DANGER Pumps build up heat and pressure during operation. Allow time associated with or near the pump.
• WARNING Do not use these pumps in water over 160º F. Do not exceed manufacturers recommended maximum performance, as this could cause the motor to overheat.
• WARNING Care fully instruction manuals supplied with motor or engine before operating or servicing.
• CAUTION Make sure lifting handles are securely fastened each time before lifting. Do not operate pump without safety devices in place. Always replace safety devices that have been removed during service or repair. Secure the pump in its operating position so it can not tip over, fall or slide.

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.
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) operate properly. Do not pump out of liquid.

Installation
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.

• Controls
  Be sure the electrical specification of the control selected properly match the electrical specifications of the pump.

• Motor connection
  All wiring of motor and control, overload protection and grounding should be in accordance with the National Electrical Code, State and Local codes. Make motor connection per label located on motor or motor manufactures manual.

• Rotation
  All units rotate clockwise as viewed from shaft end of pump. It is necessary to slide one half of the flex coupling back when checking rotation to eliminate the possibility

• Lubrication
  Lubrication not required as seal and impeller are water lubricated and need no attention.

• Priming
  Remove pipe plug in top of body and fill the pump body completely with solids free liquid. In freezing weather prime pump with warm water. CAUTION DO NOT OPERATE PUMP WITHOUT PRIMING FIRST. OPERATING DRY WILL DAMAGE SEAL.

• Starting
  To start pump, apply power to motor per the MOTOR OR ENGINE INSTRUCTIONS MANUAL.

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

• Check valve
  Disconnect suction piping and remove hex nuts and suction flange. Remove gasket, weights, screw and lockwasher and replace if worn or damaged.
  To replace, the HINGE section of gasket is at the TOP and the LARGE weight is on the pump side of gasket.
  4Body, Volute & Impeller Disconnect suction and discharge piping. Remove hex nuts and lockwashers then remove body and o-ring from pedestal.
