Piping guidelines

• All piping MUST be independently supported and MUST not rely
on the Transfer Pump for support.
• If there is no bypass valve option on your Transfer Pump, you
MUST provide a bypass valve in the process piping on any
discharge side of the Transfer Pump; since the Transfer Pump is
reversible, this may be on both sides of the Transfer Pump
depending on your application. It is recommended that the bypass
return be routed back to the tank to prevent an over-temperature
condition in the pumping fluid.
• For best performance, allow for at least five straight-pipe
diameters free of any bends or valves at any Transfer Pump inlet;
since the Transfer Pump is reversible, this may be on both sides
of the Transfer Pump depending on your application.
• If there is more than one Transfer Pump installed on the same
fluid source, ensure that each Transfer Pump has an independent
suction line to the fluid source.
• Install appropriate isolation valves in the process piping around
the Transfer Pump so that it may be properly drained and/or
removed for service. Size the valves in accordance with the
process piping – valves that are too small will reduce Transfer
Pump performance.
• Ensure that all piping and joints are free of leaks, including
vacuum leaks which may ingest air and reduce pump
performance and may reduce the pump's ability for suction and
lift.
• It is good practice to minimize both the major and minor pressure
losses in the piping system. To do so, minimize the total number
of elbow fittings, valves, and pipe bends; keep the length of the
total piping system as short as is practical; and use an
appropriately large diameter pipe size in relation to the total length
of piping.
• It is the responsibility of the user's qualified personnel to assess
the need for filtration in the pumping application. The Transfer
Pump should be installed with a 300-micron filter/strainer or finer.
Keep in mind that since the pump is reversible, you may need to
install a filter on both sides of the Transfer Pump, depending on
your application. When any filter is installed, you should monitor
the filter for life to make sure it does not become clogged during
operation, as clogged filters will significantly reduce pumping
performance. Filters that are especially fine will negatively impact
pumping performance even when new.
• It is recommended that suction and discharge pressure gauges be
installed at the inlet and outlet locations.
• Ensure that the suction piping is fully submerged below the
surface of the fluid and not too close to the surface as the high
flow of the pump will disturb the fluid surface and prevent proper
operation.

Installation and Setup

Ensure that the installation has adequate Net
Positive Suction Head Available (NPSH) for the
fluid to be pumped. See Pump Data Package.

NPSH

A
If your Transfer Pump does not include the
bypass valve option, bypass valve(s) MUST be
installed in your process piping. A bypass valve
is REQUIRED for each flow direction in which
the pump will be operated.
The FTS150/200 pumps are intended for use
with clean liquids only. Abrasives and other
solids with reduce the life of the pump. A 300-
micron strainer is recommended on the inlet
side of the pump.
Care must be taken when installing NPT
connections into aluminum. This type of pipe
connection is considered permanent and not
removable. The FTS200 pump can be
purchased with an optional 4 bolt flange
connection
Do not suspend the pump by its flanges – it
should be securely mounted to the floor or other
suitable surface. Do not allow flanges to support
the weight of the piping – ensure that all piping
is properly suspended or supported
independently of the Transfer Pump.
