Instruction Manual

Figure 2. Flooded Suction

2.1 PUMP LOCATION AND INSTALLATION

Locate pump in an area convenient to solution tank
and electrical supply.
The pump should be accessible for routine
maintenance and should not be operated in

ambient temperatures above 113°F (45°C). If the

pump will be exposed to direct sunlight, LMI

®

black,

UV resistant tubing should be installed.
This pump is cord connected and not intended
for permanent mounting to a building. However,
temporary mounting to stabilize the pump during
operation may be necessary as long as tools are
not required for the installation or removal of the
pump.

2.2 PUMP MOUNTING

The pump can be mounted in one of two ways:

A. FLOODED SUCTION

(ideal installation); or

B. SUCTION LIFT

- when suction lift is less than

5 feet (1.5 m) for solutions having a specific

gravity of water or viscosity of less than

100 cSt (centistokes). For denser or more

viscous solutions, consult distributor.

Note that suction conditions can affect the

performance of the pump. This effect is more
pronounced with lower pressure pumps. Consult
your distributor for additional information.

Your LMI

®

metering pump must be mounted

so that the suction and discharge valves are
vertical.

NEVER position pump head and

fittings horizontally

.

2.2.1 Flooded Suction

For flooded suction the pump is mounted at the

base of the storage tank. This installation is the
most trouble-free and is recommended for very
low outputs, solutions that gasify and high-viscosity

solutions. Since the suction tubing is filled with

solution, priming is accomplished quickly and the
chance of losing prime is reduced. A foot valve is

not necessary in a flooded suction installation.

WHEN PUMPING DOWNHILL OR
INTO LOW OR NO PRESSURE

SYSTEM, A BACK PRESSURE / ANTI-SYPHON DEVICE SHOULD
BE INSTALLED TO PREVENT OVER PUMPING OR SYPHONING.

NOTE:

Although popular for all solutions, LMI

®

recommends flooded suction installations for

all high-viscosity fluid applications.

INCORRECT

CORRECT

Avoid this type of false flooded suction
