Safety Warnings
Wear appropriate Personal Protective Equipment (PPE) including safety glasses when working with QED sampling
pumps. Disconnect air supply to the pump before removing the pump from the well. Do not apply more than 5 psi air
pressure to the pump if the pump is above ground.

Introduction
The Well Wizard dedicated bladder pump system includes both dedicated down-well components
and portable above ground components. The water contacting components are dedicated; they
remain installed in each well. The pump controller, compressed air or gas source and water
quality monitoring components are portable and are transported from well to well.
This document is intended to assist you with the proper installation of your Well Wizard dedicated
bladder pump system, covering key steps and installation tips. Your system may have some
custom components that may require some deviation from these instructions. Instructions for
those components will typically be included on an accompanying separate instruction sheet.
If you have any questions or problems while you’re in the field and can’t find a solution, please
call QED Customer Service at the phone numbers above. For questions that aren’t urgent, you
can send an email to us at s[email protected]m.

Well Wizard Bladder Pump Models
A Well Wizard® dedicated bladder pump system is an air-actuated bladder pump
that you permanently position in the well.
The pump is typically positioned with the pump inlet midway in the screened section of the
well, suspended by twin-bonded tubing that supplies air to the pump and conveys the water
sample to the well cap. Whenever possible, the pump systems are shipped already
preassembled to the tubing and the well cap assembly. Several different models of Well
Wizard® bladder pumps are available.
1000 Series Pump
Field service of the small diameter 1000 Series pump is generally not recommended as reassembly may
result in damage. Please contact QED Technical Support at 1-800-624-2026 or +1-734-9995-2547 for more
information on how to service these pumps.
1100 Series Pumps
The 1100 Series pumps can be disassembled for field service and include 4 major components:
• Discharge assembly (PVC, stainless steel or Teflon®)
• Inlet assembly (PVC, stainless steel or Teflon)
• Bladder cartridge assembly (Teflon bladder or Well Wizard Zero non-fluoropolymer bladder)
• Pump Body (PVC, stainless steel or Teflon)
You can disassemble the major components of the pump without tools by unscrewing the inlet
and discharge assemblies by turning them counter-clockwise and pushing the bladder cartridge
out of the pump body. The bladder cartridge can be replaced as a complete assembly on
dedicated models; the bladder can be removed and replaced separately on portable models.
1200 Series Pumps
The 1200 series pumps can be disassembled for field service and include 2 major components
• Bladder and check valve assembly (either Teflon and stainless steel or PVC and
stainless steel)
• Pump Body (stainless steel)
The 1200 Series pumps bladders can be replaced and will require tools for disassembly (refer to
the instructions included with the field-replaceable bladder kit).
1300 Series Pumps
The small diameter 1300 series pumps require snap ring pliers to disassemble, and field service is generally
not recommended. Please contact QED Technical Support at 1-800-624-2026 or +1-734-9995-2547 for
more information on how to service these pumps.
1500 Series Pumps
The P1500 pump is a longer version of the 1200 Series pump. This pump has two major components.
• Bladder and check valve assembly (either Teflon and stainless steel or PVC and
stainless steel)
• Pump Body (stainless steel)
The 1500 Series pumps bladders can be replaced but may require factory service; contact QED
Technical Support at 1-800-624-2026 or +1-734-9995-2547 for more information on how to
service these pumps.

How a Bladder Pump Works
The bladder pump has two alternating cycles
called Discharge and Refill.
Discharge Cycle
During the discharge cycle, water within the pump is
pushed to the surface by pressurized air or gas delivered to
the pump through the air supply tubing. When the
pressurized air fills the chamber between the pump body
and the bladder, it squeezes the bladder, closing the
bottom check valve and lifting the upper check valve,
pushing water up the discharge tubing to the surface. When
the full volume of the bladder is discharged or the cycle is
ended by the controller, the upper check valve closes to
prevent water in the tubing from draining back into the
pump.

How a Bladder Pump Works
Refill Cycle
During the refill cycle, the pressurized air or gas within the
pump is vented back up to the surface through the air
supply tubing. When the air pressure within the pump falls
below the hydrostatic pressure, the bottom check valve
opens and allows water to enter the pump, filling the inside
of the bladder.
Caution: A Well Wizard® pump bladder can be damaged by
sand or solids. An inlet screen is recommended for all
applications, especially when the pump inlet is located close
to the bottom of the well. The Well Wizard 10-year warranty
does not apply if an inlet screen is not used.

Twin-Bonded Pump Tubing, Inlet Screens and Well Caps
Pump Tubing
A ground water sample is only as good as the tubing it runs through. Your Well Wizard® system should be
equipped with one of the following types of superior-quality tubing from QED:
• High Density Polyethylene (HDPE)
• Teflon® -lined polyethylene
• Teflon®
Most tubing is supplied as a bonded pair (air supply and discharge) to make installation easier
and help to prevent other equipment such as water level measurement tapes from becoming
entangled with the tubing.
Unless your order specified that you wanted bulk tubing, the tubing for your Well Wizard
bladder pump is pre-cut to the correct length for your well based on the well data you provided.
Inlet Screen
An inlet screen can protect the bladder in your Well Wizard pump by preventing sand from
contacting the bladder and ensure proper performance by keeping larger sand particles out of
the check valves. The use of an inlet screen extends the pump warranty to ten years.
Well Cap
The pump and tubing are connected to a well cap that support the weight of the system and
provides connections for the air supply and water discharge. There are two terminal fittings inside
the well cap (see figure 4 below).
• A compression style bore-through fitting for the discharge line.
• A brass quick-connect nipple for the pump air supply line.
There are a wide variety of well cap designs to accommodate the majority of well completion
designs, both above grade protective outer casing and at-grade vault boxes. Various designs
include recessed caps for low clearance applications in vault boxes, slip caps for use in outer
protective casings, locking caps to help prevent unauthorized access to the well, and sealing
caps to help prevent surface water from entering the well. Consult QED’s Customer Service or
Sales representatives to determine the best design for each well at your site.
