Self-Priming Adaptor
Installation, Operation, Repair and Parts Manual
Description
Self-priming adaptor (SPA) is a low pressure tank that
provides air separation from the liquid being pumped.
Air is vented out the top port and liquid is redirected from
the lower port back to the centrifugal pump inlet port.
Recirculation through the centrifugal pump provides fast
self-priming of the inlet vacuum hose to the centrifugal pump.

Plumbing Installation
Mount self-priming adaptor in a secure location.
Optional bracket kit available, PN 3430-0700.
Max. SPA Height: Top of SPA no higher than bottom of
fill port.
Min. SPA Height: Top of SPA mounted higher than top of
casting on inlet port to support gravity feed system.
Max. Hose Distance: Hose length between SPA and
pump inlet should be no more than three meters (10 ft.).
Vent Line minimum diameter: 25mm (1 in.) diameter
raised a 1/2 meter (20 in.) above SPA before entering
tank. Use clear hose if possible as indicator for priming.
Return Line: Return line is subject to suction vacuum
pressure. Use hose rated for vacuum pressure of discharge -75 cm (-30 inches) Hg.

Min. Height
Mount self-priming adaptor in a location within 3 meters
(10 ft.) of the pump inlet. The self-priming adaptor chamber is rated as a low pressure tank and is not designed to
accept pressures over 3 Bar (45 PSI). System should be
plumbed to protect from over-pressurization.
Use of two-way and/or three-way valves can be used to
direct flow through the self-priming adaptor (SPA) during
priming operation. The vent line can be sized to be used
to fill the tank once the pump has primed. Use 32 mm
(1-1/4 in.) max ID vacuum hose for return line from the
SPA to the pump inlet port. Directing circulation flow from
SPA directly towards pump inlet impeller eye will greatly
increase overall priming performance and stability.
The return line from the SPA to the pump inlet must be
hose rated for vacuum pressure.

Return Line
Manifold systems will function well with SPA. It is important
to direct the return line from the SPA to the pump inlet in a
manner as to jet the flow into the pump impeller to ensure
good priming performance and stability. Use of Y fittings
at the inlet of the pump will aid in accomplishing a posi-
tive flow towards pump impeller. To ensure that the fluid
necessary to induce priming does not cascade out of the
system, be sure that all other systems are turned off during
priming (boom, agitation, chemical eduction).
Operation and Maintenance
The vent line can also be used to complete the circuit for
filling the sprayer tank. In many systems, the vent line provides an efficient path to the tank and greatly decreases the
amount of time to fill the tank. If the vent line is used to fill the
tank, the return line is shut off once the inlet fill line is primed.
To operate the pump in spray mode, close off self-priming
circuit and fill line, then open tank valve.
To facilitate pump priming, water or fluid is circulated
through eye of the impeller and pump. The attached
SPA allows for entrained air to percolate out of the liquid
being circulated and releases the air back to atmosphere
through the vent line. The liquid is returned back to the
pump inlet, thereby evacuating the inlet suction line of
air. Once the pump is primed, pressure increases in the
separation chamber. The operator then closes off the
circulation path to the pump inlet and SPA and redirects
the pump flow to fill sprayer tank.

Operation and Maintenance
A simple way to test the system is to insert a vacuum gauge on the fill port to measure
the amount of vacuum the pump is producing. When the pump is running, and water is
being circulated through the SPA, a reading of -63 to -75 cm (-25 to -30 inches) of Hg
vacuum pressure is expected. Simply placing your hand over the inlet port will also give a
good indication of operation.
Pump speed can also increase priming rates. Speed of pump should operate in the range
of 3500 to 5000 RPMs to get good results.
Having a clear vent line and return line hose can be a good indicator for how the SPA is
working and when priming is achieved. Simply listening to the pump operation will also
indicate when priming has occurred; a sudden change in RPM is associated with pump
flow when the pump is primed.
Troubleshooting Guide
Symptom
Probable Cause(s)
Corrective Action
Pump fails to prime.
No liquid or low liquid level for water
circulation to induce priming.
Open clean water tank valve to fill
priming circuit with adequate water
to operate priming circuit. Water will
flow out vent line or fill port if filled
to an adequate level.
Valves are not open to provide path
for water circulation through priming
system.
Check valves to make sure they are
in correct position for priming.
Vacuum leaks.
Check that valve to tank is closed
and valve on fill line is open.
Pump operating speed too low.
Increase pump speed (4000 to 5000
RPM).
Low liquid level in SPA.
Crack open clean water tank to fill
tank and priming circuit to acceptable liquid level.
Too much air is returning with liquid
to pump short-circuiting priming.
Reduce liquid flow back to pump by
reducing return line by one size ID.
Pump operating speed too high.
Reduce pump speed during priming.
Water for priming is initially
adequate but cascades away
from priming circuit.
Check to make sure water is not
finding another discharge path,
such as agitation or to boom.
Surging during priming.
Vacuum decreases over time during
priming operation.

Priming rates are dependent on optimal plumbing systems,
length and size of inlet hose, and rotational speed of pump
impeller. Actual rates may vary depending on system
configuration.
Comparison test results were produced in lab under
controlled environment. Total lift capacity of pumps is
expected to be 7.6 meters (25 feet) or more.
Because pump is moving water, the system is able to
develop 1.7 bar (25 PSI) pressure against any restriction
in vent line during priming at no lift and .34 bar (5 PSI)
pressure at 7 meters (23 feet) of lift.
