SERVICE AND OPERATING MANUAL
®
Model SB11/2-H
Type 1
PLEASE NOTE!
The photos shown in this manual are for general instruction only. Your specific
model may not be shown. Always refer to the parts list and exploded view drawing
for your specific model when installing, disassembling or servicing your pump.
PRINCIPLE OF OPERATION
The SandPIPER pump is powered by hydraulic fluid which alternately pressurizes the inner sides of the two diaphragm chambers while simultaneously exhausting the opposite inner chambers causing the diaphragms, which are connected by a
shaft, to move endwise. Since hydraulic pressure is applied over the entire surface
of the diaphragm which is forcing liquid to be discharged by its other side, the diaphragm is operating under a balanced condition during the discharge stroke. This
allows the unit to be operated at discharge heads over 200 feet (61 meters) of water
head.
Since the diaphragms are connected by means of a shaft secured by plates to the
center of the diaphragms, while one diaphragm is being pressurized to perform
discharge stroke, the other diaphragm is being pulled to perform the suction stroke
in the opposite chamber. The suction stroke becomes the only unbalanced load
applied to diaphragms during operation, thereby providing much longer life than
mechanical operated diaphragms under similar conditions. Since the suction lift
portion of the operation is essentially the only load applied to diaphragms, it becomes obvious that the longest possible diaphragm life will be attained by the least
amount of suction lift. ALWAYS KEEP THE UNIT AS CLOSE TO THE LIQUID BEING PUMPED AS POSSIBLE. POSITIVE SUCTION HEAD IN EXCESS OF 10 FEET
(3.05 METERS) OF LIQUID SHOULD ALSO BE AVOIDED FOR GOOD DIAPHRAGM SERVICE LIFE.
Alternate pressurizing and exhausting of the diaphragm chamber is performed by
means of an externally mounted, pilot operated, four way, spool type distribution
valve. When the spool is at one end of the valve body, inlet hydraulic pressure is
connected to one diaphragm chamber and the other diaphragm chamber is connected to the exhaust. When the spool is moved to the opposite end of the valve
body, the porting of chambers is reversed. The distribution valve spool is moved
from one end position to the other in the valve body by means of an internal pilot
valve which alternately pressurizes one end of the 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 coming in contact with the end of the
pilot valve spool and pushing it into position for shifting of the air distribution valve.
Chambers are manifolded together with a suction and discharge check valve for
each chamber to maintain flow in one direction through the pump.
INSTALLATION
Locate the pump as close to liquid being pumped as is practical to keep suction
line length and number of fittings to a minimum. DO NOT REDUCE SUCTION LINE
SIZE except for very low rates or where higher velocities are required to keep
pumped material in suspension in the carrying liquid. For installations involving the
use of rigid piping, short flexible sections of hose are recommended between pump
and piping. This reduces piping strains and vibrations.
OPERATION
Your SandPIPER pump has been tested prior to shipment and is ready for use as
received.
The SandPIPER is completely self-priming from a dry start up to suction lifts of 15
feet (4.57 meters). For priming at suction lifts in excess of 15 feet (4.57 meters), fill
the chambers with liquid prior to operation.
IMPORTANT
Read these instructions completely,
before installation and start-up. It is the
responsibility of the purchaser to retain
this manual for reference. Failure to
comply with the recommendations
stated in this manual will damage the
pump, and void factory warranty.
WARNING
Take action to prevent static sparking.
Fire or explosion can result, especially
when handling flammable liquids. The
pump, piping, valves, containers or
other miscellaneous equipment must be
grounded.
BEFORE OPERATION
Before pump operation, inspect all
gasketed fasteners for looseness
caused by gasket creep. Retorque loose
fasteners to prevent leakage. Follow
recommended torques stated in the card
attached to the new pump.
DANGER
Before doing any maintenance on the
pump, be certain all hydraulic pressure
is completely vented from the pump,
suction, discharge, piping, and all other
openings and connections. When used
for toxic or aggressive fluids, the pump
should always be flushed clean prior to
disassembly. Be certain that approved
eye protection and protective clothing
are worn all times in the vicinity of the
pump. Failure to follow these
recommendations may result in serious
injury or death.
HAZARD WARNING
POSSIBLE EXPLOSION HAZARD can
result if 1, 1, 1,-Trichloroethane,
Methylene Chloride or other
Halogenated Hydrocarbon solvents are
used in pressurized fluid systems
having Aluminum or Galvanized wetted
parts. Death, serious bodily injury and/
or property damage could result.
Consult with the factory if you have
questions concerning Halogenated
Hydrocarbon solvents.

PRESSURE SUPPLY
Do not connect the unit to a pressure supply in excess of 125 PSI (8.61 bars).
Connect the pump inlet port, denoted by a P on the end cap, to a hydraulic supply of
sufficient capacity and pressure as required for desired performance.
HYDRAULIC FLUID RETURN
The SandPIPER pump has two return ports. One is on the intermediate and the
other is on the end cap, denoted by a T. Both ports must be connected to the
hydraulic reservoir, either separately or manifolded into a common line. Piping for
the return should not be smaller than 1" pipe size.
SUCTION STRAINER
When pumping liquids that may contain solids larger than 1/4" (.635 cm) in diameter, a suction strainer should be installed to avoid clogging of ball valves.
MAINTENANCE AFTER USE
When SandPIPER is used to handle materials that settle out or transform from
liquid to solid form, care must be taken after each use and during idle periods to
remove and flush these materials as required.
To drain liquid from pump, turn the unit over on the suction and discharge manifold side. This position puts the chamber ports down and allows ball checks to fall
away from the seats to permit complete drainage of the unit. This procedure is
important to insure complete draining in freezing weather.
On permanent installations, chambers can be drained by removing the pipe plugs
in the outer chambers.
CHECK VALVES
For best priming and most efficient pumping performance, it is important to maintain check valves and valve seats in good condition for proper sealing. Need for
inspection or service ot ball valves is usually indicated by poor priming, unstable
cycling, reduced performance, or when the pump cycles but will not pump.
Inspection and service of check valves requires the removal of six bolts which
provides access to all four ball valves and both suction and discharge valve seats.
New rubber ball check valves are 2
ment when worn to approximately 2" (5.08 cm) diameter (Fig. 1).

/4" (5.715cm) diameter and will require replace-
CAUTION
Should a diaphragm fail, the product
and/or fumes from the product being
pumped can enter the hydraulic side of
the pump or the hydraulic fluid can enter
the product side of the pump depending
on which side offers the least
resistance. The hydraulic fluid should
be periodically checked for pumped
product contaminants and/or a
changing of the hydraulic fluid level in
the reservoir. Shut off valves should be
installed on all piping, hydraulic and
product sides, to and from the pump.
These valves should be closed when the
unit is going to be idle for an extended
time to ensure that a siphoning effect
does not develop.
Figure 1: Inspection of check valves.
DIAPHRAGMS
Need for inspection or service of a diaphragm is usually indicated when the unit
pumps from one chamber only and hydraulic fluid is discharged out the pump discharge port or when liquid being pumped is discharged through the hydraulic return
line. To service diaphragms, remove the V-Band clamp and two hex nuts which
secure the chamber port to the manifold. To remove diaphragms, loosen the diaphragm assembly (outer plate, diaphragm, inner plate) by turning out of the shaft
using a wrench. A 1" (2.54 cm) square lug is provided on the outer plate for this
purpose. Removal of the opposite outer chamber will permit removal of the second
diaphragm assembly and shaft as a unit. To disassemble the diaphragm assemblies, clamp the inner diaphragm plate around the outer diameter between the jaws
of a vise while you turn the outer diaphragm plate loose using a wrench. Interior
components consisting of shaft seals and sleeve bearings are now accessible for
service if required.
All procedures for reassembling the diaphragms are in reverse of previous instructions for disassembly. The diaphragms are to be installed with their natural
bulge outward or toward the outer diaphragm plate. Make sure the inner plate is
installed with the flat face against the diaphragm (Fig. 2).
After all components are in position in the vise and hand tight, tighten with a
wrench to approximately 40 ft. Ibs. (5.53 kilograms/meters) torque. After each diaphragm assembly has been made, thread one assembly into the shaft (hold the shaft
near the middle in a vise having soft jaws to protect finish). Install this sub assembly
into the pump and secure by placing the outer chamber on the end with the diaphragm. This will hold the assembly in place while the opposite side is installed.
Make sure the last diaphragm assembly is torqued to 30 ft. Ibs. (4.147 kilograms/
meters). This final torquing will lock the diaphragm assemblies together. Place the
remaining outer chamber on the open end and secure. Snug the flange bolts of the
chamber to port manifold to square the flanges before the final tightening of the V-

Band clamps. Tighten the flange bolts securely after tightening the V-Band clamp.
IMPORTANT: Do not tighten the V-Band clamp without loosening the manifold flange
bolts at the outer chamber ports. The chamber flange may be broken.
HYDRAULIC DISTRIBUTION VALVE
The spool is closely sized to the sleeve, but should slide freely. Accumulation of
dirt and silting can prevent the spool from moving freely or stick in a position that will
prevent the pump from cycling. Remove the hydraulic valve body from the adapter
block, remove the end caps, and push out the spool. Wash the spool in cleaning
solvent or lubricant. Coat the spool with a light oil and reassemble making sure the
spool slides freely in the valve body.
PILOT VALVE
This assembly is reached by removing the adapter end cap and adapter block.
The pilot valve body assembly is then free to be lifted out of the intermediate housing
and inspected. The pilot valve spool can be pushed out of the sleeve exposing the orings.
To inspect the sleeve, remove the retaining ring and slide the sleeve out of the
pilot valve body. The o-rings on the spool and sleeve should be replaced if worn and
lubricated with an o-ring lubricant before re-assembly.
When reinserting an externally serviceable pilot valve, push both plungers out of
the path of the pilot valve so that they and the pilot valve are not damaged.
PILOT VALVE ACTUATOR
The bushings for the pilot valve actuators thread into the intermediate bracket
from the outside. The plunger may be removed for inspection or replacement from
the inside by removing the adapter end cap, adapter block and the pilot valve body
assembly from the pump. The plungers should be visible as you look down into the
intermediate from the top. Depending on their position. you may find it necessary to
use a fine piece of wire to pull them out.
Under rare circumstances, it may become necessary to replace the o-ring seal. If
it cannot be removed in much the same manner as the plunger, the bushing can be
turned out through the inner chamber by removing the manifold assembly and the
outer chamber to reach the bushing.
IMPORTANT
Do not tighten the V-Band clamp
without loosening the manifold flange
bolts at the outer chamber ports. The
chamber flange may be broken.
CAUTION
This pump is pressurized internally
during operation—always make certain
all bolting is in good condition and that
all correct bolting is reinstalled during
assembly.
CAUTION
Always disconnect hydraulic supply to
relieve pressure before disassembling
any portion of pump.
TROUBLE SHOOTING
PROBLEM: Pump cycles but will not pump. (Note: higher suction lifts require faster
cycling speed for priming.)
POSSIBLE CAUSES:
A. Air leak in the suction line.
B. Excessive suction lift.
C. Check valve not seating properly.
D. Leakage at joint of suction manifold or elbow flange.
E. Suction line or strainer plugged.
F. Diaphragm ruptured.
PROBLEM: Pump will not cycle.
POSSIBLE CAUSES:
A. Discharge hose or line plugged, or discharge head requirement greater than
supply pressure. (Disconnect discharge line to check.)
B. Spool in distribution valve not shifting. (Remove end cap and check spool—must
slide freely.)
C. Diaphragm ruptured. (Hydraulic fluid will most often escape out discharge line in
this case.)
D. Blockage in diaphragm chamber preventing movement. (Shut off hydraulic supply
and reopen after pressure is relieved.)
PROBLEM: Uneven discharge flow. (Indicates one chamber not operating properly.)
POSSIBLE CAUSES:
A. Check valve not seating properly in one chamber.
B. Diaphragm failure in one chamber.
C. Air leak at suction manifold joint or elbow flange one side.
WARRANTY: This unit is guaranteed for a period of five years against defective
material and workmanship.
