Installation
Note: Blackmer power pumps must only be installed in systems designed by qualified
engineering personnel per NFPA 30 or 30A. system design must conform with all
applicable regulations and codes and provide warning of all system hazards.
Pre-installation Cleaning
Location and Piping
Pump life and performance will be significantly reduced when installed in an improperly
designed system. Before starting the layout and installation of the piping system, review the
following suggestions:
1 Locate the pump as near as possible tot he source of supply to avoid excessive inlet pipe
friction.
2 The inlet line should be at least as large as the intake port on the pump. It should slope
downward to the pump, and should not contain any upward loops. Eliminate restrictions such
as sharp bends; globe valves, unnecessary elbows, and undersized strainers.
3 A strainer must be installed in the inlet line to protect the pump form foreign matter. The
strainer should be located at least 24 inches (0.6m) from the pump, and have a net open area of
at least four times the area of the intake piping. Strainers must be cleaned regularly to avoid
pump starvation.
4 The intake and discharge piping system must be free of all leaks.
5 Expansion joints, placed at least 36 inches (0.9m) from the pump, will compensate for
expansion and contraction of the pipes. Contact the flexible connector/nose manufacturer for
required maintenance/care and design assistance in their use.
6 All piping and fittings must be properly supported to prevent any piping loads from being
Hazardous voltage can shock, burn or cause death.
- Install, ground and wire to local and National Electrical Code requirements.
- Install an all-leg disconnect switch near the unit motor.
- Disconnect and lockout electrical power before installation or service.
- Electrical supply MUST match motor nameplate specifications.
- Motors equipped with thermal protection automatically disconnect motor electrical
circuit when overload exists. Motor can start unexpectedly and without warning.
WARNING
!
Foreign matter entering the pump will cause extensive damage. Ensure that the
supply tank and intake piping have been cleaned and flushed prior to pump
installation and operation.
