conductance. The probe is installed into the bottom-
most 1/4" NPT pipe tee on SANDPIPER pumps
equipped with the Containment Duty spill containment
option, or through the bottom boss in the spill
containment chamber on SANDPIPER Model ST1-A
and ST1½-A pumps. When the pumping diaphragm
fails, the probe is exposed to the pumped liquid. This
produces a low current of 1.2 volts DC (<1 milliamp)
which signals the control unit. One of two indicator lights
signal which pumping diaphragm has failed and which
spill containment chamber has been contaminated by
the pumped fluid.
The control unit can easily be wired to an audible
alarm or a pump shutdown mechanism. An optional
External Output Junction is available, allowing the leak
detector to be mounted near the pump or in a remote
location. The 3-lead wire part number 150-027-000 is
supplied in 15-foot lengths and the probe assembly
part number 628-002-000 (2 required) in 2-foot lengths.
When the Warren Rupp Electronic Leak Detector is
installed on standard pumps (without spill containment)
the probes are inserted into the bottom boss plugs on
the inner chambers.
NOTE: The Warren Rupp Leak Detector will detect
any moisture that pools at the bottom of the inner
chamber. Air supplies with high moisture content will
deposit at the bottom of the inner chamber. This will
cause the probe to send false signals of diaphragm
rupture to the control unit. When the leak detector is
used to detect diaphragm failure it is recommended
that an air dryer be installed in the air supply line to
lessen the chance of false signals.

Hazardous voltage.
This Leak
Detector is an electrical device. It should
be wired by only qualified, licensed
electricians. The cover should never be
removed except by authorized, licensed
electricians. Failure to heed this warning
may result in electric shock, personal
lasting injury or death.
Power shall be disconnected before
enclosure is opened.
Enclosure shall be closed before power
is restored.

The Warren Rupp Electronic Leak Detector consists
of a modular control unit encased in a watertight
enclosure, two detection probes, and a watertight
enclosure. All of these items are wired together as
noted on the schematic illustration Figure A on page 2.
The Warren Rupp Electronic Leak Detector senses
pumped liquid entering either the inert fluid-filled spill
containment chambers of the pumps, or the inner
chambers of standard pumps.
SANDPIPER ® Containment Duty (spill containment)
pumps are designed with a two-fold purpose:
1. In the event of a ruptured pumping diaphragm, the
pumped fluid is prevented from entering the
compressed air system of the pump because it is
contained by a second diaphragm.
2. In the event of a driver diaphragm failure, only
the inert filler fluid in the spill containment chamber
is exhausted through the muffler. The pumped liquid
is prevented from entering the air system and the
environment by the pumping diaphragm, and compressed
air is prevented from contaminating the pumped liquid.
When the Warren Rupp Electronic Leak Detector
is installed in the inert fluid-filled spill containment
chamber, it provides an early warning of failure of the
pumping diaphragm.
The leak detector works on the principle of
12-32 VDC
