Roper F Series - System Pressure and Hazardous Fluids; Plumbing Guidelines; Mounting Base Requirements; Pump and Drive Assemblies

4
NOTICE: These are general guidelines and do not cover all possible situations. It is the
responsibility of the system integrator to apply this product properly.
 System Pressure & Hazardous Fluids
1. Disconnecting fluid or pressure containment components during pump operation can cause property damage,
serious personal injury, or death.
2. Failure to relieve system pressure prior to performing pump service or maintenance can cause property
damage, serious personal injury or death.
3. If pumping hazardous or toxic fluids, system must be flushed and decontaminated, inside and out, prior to
performing service or maintenance.
 Plumbing
1. The inlet pipe should be as short and straight as possible to minimize suction pressure losses. Excessive
restrictions at the inlet can cause cavitation resulting in poor performance, noise, vibration, or pump damage.
2. Slope the inlet plumbing appropriately to avoid air pockets.
3. Plumbing weight, misalignment with the ports or thermal expansion can exert excessive force on the pump.
Plumbing must be properly supported and aligned with expansion joints, if required, to minimize these forces.
4. To prevent over pressure situations, install a relief valve as close to the pump outlet as possible. Install the
relief valve before any shut-off valves.
DO NOT use Thread Seal (Teflon
®
) tape on pump port threads.
 Mounting Base
1. Mount the unit on a rigid, heavy base to provide support and absorb shock. Bases should be designed for
high rigidity; not just strength.
2. The pump feet were not designed for mounting to concrete and do not have enough contact area to prevent
concrete from failing. When mounting to cement or concrete, use a steel baseplate to distribute the mounting
stress over an area large enough to prevent the cement from failing. Grout it in place.
 Pump and Drive Assemblies
1. Assure adequate guards have been installed to prevent personnel contacting moving components.
2. Follow all OSHA, Federal, State, and local codes.
 Check Alignment of Pump to Driveline
Excessive misalignment can overload the pump input shaft and cause premature failure. The figures below show
parallel and angular misalignments.
