
Once fitted and wired allow water to flow into the pump, only bump the motor for rotation
at this time. Caution….bumping a dry motor will damage the seals and is not a
warranty event. Reverse terminal leads as required.
Start-up and Operation:
1. The pump suction strainer needs to be filled with water before starting the Pump (Tower
Clean Systems only). Partially close (approximately 25%) the discharge valve and make
sure that the suction valve is fully open. Start the pump and observe the pressure gauge
which reads the discharge pressure of the pump at the inlet of the separator. The needle of
the gauges might flicker for a few seconds and will then settle, indicating that any air in the
system is being bled off naturally. If it continuously flickers and if the pump cavitates for
more than a minute, bleed-off air from the system.
Once pressure has reached 20 psi or more (Tower Clean System) or 15 psi (Side Stream
System), slowly open the discharge valve to ensure proper pump operation. If the valve
cannot be fully opened without the pump cavitating, be sure there are the correct number
of sweeper jets installed downstream of the Tower Clean System. In a Side Stream System
application the valve may need to be adjusted to ensure proper backpressure on the pump.
This is normal .
NOTE:
Make sure that all suction valves (from the source of water to the pump intake) are fully
opened when the pump is running. Operating the system with a partially closed suction
valve can damage the pump and/or affect the system's performance. Each model requires
a minimum liquid submergence level (above the pump intake) to meet the pump's Net
Positive Suction Head Required (NPSHR) to avoid air intrusion or cavitation (vortexing at
point of source). See appropriate pump curve included with your submittal. This is also very
important when Amiad sweeper jets are in use.
Entrapped air will always seek the highest elevation in the system. A valve in the system
outlet will be at the highest elevation. When partially opened during start-up, it will relieve
air from the system.
The Solids Recovery System, if installed with your system, must also be primed and
vented at the solids collection vessel (BGFS). Please see BGFS operating procedure
in this manual.
DO NOT DRY-RUN THE PUMP . All pumps require a flooded suction before
starting, using water as a lubricant for their seals. John Crane-type seals (e.g.,
Silicon Carbide Seals) can wear out in 20 seconds of dry operation. It only takes a
small amount of water to lubricate the seal, and it vaporizes during pump
operation. Also, when replacing the seals, avoid touching the Silicon Carbide faces;
oils, moisture and dirt from your fingers escalate seal wear.
