SANDPIPER® Containment Duty Pumps: Sealless Safety

This pump is part of the Containment Duty Pumps. It is specially tted with PTFE diaphragms as well as elastomeric or elastomeric/PTFE driver diaphragms. The liquid-lled
spill chambers provide an additional chemically-resistant barrier, should a pumping diaphragm fail. The Spill Containment design gives the pump user advanced warning of
diaphragm failure, before pumpage can damage the air valve or be released into the work environment. Three optional leak detectors available for this model:

• Mechanical VIP Leak Detector* 031-025-000 • Electronic Leak Detector* (115V) 032-043-000 • Electronic Leak Detector* (220V) 032-043-000

The Containment Duty pumps offer many different levels of materials and spill monitoring devices designed to t a variety of applications and budgets.

Maximum and Minimum Temperatures are the limits for which
these materials can be operated. Temperatures coupled with
pressure affect the longevity of diaphragm pump components.
Maximum life should not be expected at the extreme limits of
the temperature ranges.

Materials

EPDM Shows very good water and chemical resistance. Has poor resistance to oil and solvents, but is fair in

ketones and alcohols.

NEOPRENE All purpose. Resistant to vegetable oils. Generally not affected by moderate chemicals, fats,
greases and many oils and solvents. Generally attacked by strong oxidizing acids, ketones, esters, nitro
hydrocarbons and chlorinated aromatic hydrocarbons.

PTFE Chemically inert, virtually impervious. Very few chemicals are known to react chemically with

PTFE: molten alkali metals, turbulent liquid or gaseous uorine and a few uoro-chemicals such as
chlorine triuoride or oxygen diuoride which readily liberate free uorine at elevated temperatures.

FKM (Fluorocarbon) shows good resistance to a wide range of oils and solvents; especially all aliphatic,
aromatic and halogenated hydrocarbons, acids, animal and vegetable oils. Hot water or hot aqueous solu
tions (over 70°F) will attack FKM.

PRINCIPLE OF OPERATION

All Warren Rupp SANDPlPER pumps, including this Containment Duty SANDPlPER
pump, operate on the same basic principle. They are designed to be powered by compressed
air only which alternately pressurizes the inner side of one diaphragm chamber while
simultaneously exhausting the other inner chamber. The diaphragms are connected by
a common rod; when the inner side of one diaphragm chamber is pressurized, moving
the diaphragm outward on a discharge stroke, the opposite diaphragm is pulled inward
on a suction stroke.

Alternate pressurizing and exhausting of the diaphragm chamber is accomplished
with an externally mounted pilot operated, four way, spool type, air distribution valve.
When the spool is at one end of the valve body, inlet air pressure is connected to one
diaphragm chamber while the other diaphragm chamber is exhausting. When the spool
is moved to the opposite end of the valve body, the porting of chambers is reversed. The
air distribution valve spool is moved from one end position to the other in the valve body
by an internal pilot valve which alternately pressurizes one end of the air distribution valve
spool while simultaneously exhausting the other. The pilot valve is positively shifted at
each end of the diaphragm stroke by the diaphragm plate contacting the end of the pilot
valve spool. This pushes it into position to shift the air distribution valve.

In all SANDPlPER pumps, this reciprocating diaphragm movement creates an alternating
suction and discharge action in the outer diaphragm chamber and the pumped material. A
manifold with a suction and discharge check valve for each chamber serves as a common
inlet and outlet for the pump.

This Containment Duty SANDPlPER unit differs from other SANDPIPER units only in
that it utilizes four (4) diaphragms instead of two (2). Two rod-connected diaphragms are
the driver diaphragms. The other two (outermost) diaphragms are the actual pumping
diaphragms. Each driver diaphragm (of neoprene or other elastomer), and the pumping

diaphragm (of PTFE), are separated by a chamber lled with liquid which transmits the

reciprocating motion of the driver diaphragm to the pumping diaphragm. The PTFE pumping
diaphragms, in turn, create the alternating suction and discharge action in the outer

diaphragm chambers, and are the only diaphragms in contact with liquid being pumped.

Model ST40 Type 4

Original Instructions

INSTALLATION PROCEDURES

CAUTION: This pump should not be applied in pumping applications where the driver

liquid coming in contact with the pumped liquid would create a hazardous condition.
This contact will occur if a PTFE pumping diaphragm fails since this diaphragm normally
separates the two liquids. Also note that care must be taken to guard against the operation
of this unit if it has been subjected to freezing temperatures. If the driver liquid freezes,
possible diaphragm failure may result.

Locate pump as close to product to be pumped as is practical to keep length of suction

line and number of ttings to a minimum. DO NOT REDUCE SUCTION LINE SIZE except
for very low ow rates or where higher velocities are required to keep pumped material

in suspension in the carrying liquid.

This unit is completely self-priming from a dry start up to a static suction lift of 10

feet (3.05 meters). For priming at suction lifts in excess of 10 feet (3.05 meters), ll the

pumping chambers with liquid prior to operation. POSITIVE SUCTION HEAD IN EXCESS
OF 10 FEET (3.05 METERS) OF LIQUID SHOULD ALSO BE AVOIDED FOR BEST
DIAPHRAGM SERVICE LIFE.
