System Components

A Geotech Bladder Pump consists of three main parts (see figure 2):
- The Bladder Cartridge Assembly
- Pump Housing
- Intake Screen
*

Optional: Drop Tube Intake Assembly

Bladder Cartridge Assembly

Geotech’s 1.66” (4 cm) Bladder Cartridge Assembly (for 18”/46 cm and 36”/91 cm lengths)
is factory assembled and tested, and is designed to be field replaceable.

The .850

” (2 cm) and .675” (1.7 cm) Bladder Cartridge’s are easily replaceable see,

Chapter 4: System Maintenance.

Pump Housing

The bladder pump housing is constructed of electro polished 316 Stainless Steel. The
housing components consist of threaded top and bottom caps, and the housing tube.
Viton O-rings provide the high pressure seals between the end caps and the housing tube.

Intake screen

The intake filter screen is constructed of 316 Stainless Steel and is easily removable for
field maintenance. The intake filter screen is intended to protect and extend the life of the
bladder material (see warranty).

*

Optional: Drop Tube Intake Assembly

An optional drop tube can be used to sample from depths below the specified maximum
sampling depth. The drop tube assembly connects a remote intake to the pump through a
tube connected to the pump inlet. The intake depth can be any custom length of tubing.
The pump assembly itself must still be submerged below the water level. This means the
depth to water cannot exceed the maximum pumping depth of the pump.

Be sure to read and understand your portable generator and/or
portable air compressor user manual for proper installation and
operation and Earth grounding instructions. If using portable
compressed gas tanks, be sure to exercise proper caution, use safety
protection devices as outlined by the supplier, and observe any
additional safety requirements mandated by local jurisdiction.
