Four Performance Ranges
Waterra® pumps are available in four performance ranges,
depending on the diameter of tubing and footvalve. Choose from High Flow System Standard
Flow System, Mini Flow System and Micro Flow System. The larger the tubing, the greater
the flow rate and depth capacity. Within each flow range is an assortment of footvalves
and tubing for different requirements. |
 |
|
Standard Flow
The Standard Flow System is the most popular
inertial pump. This system is best suited for 2" monitoring wells and can
provide lifts up to 150 feet. Flow rates can be as much as 1 gallon per
minute. |
 |
|
Standard Flow - D-25
This is the most commonly used Waterra® flow system. The footvalve used is a
Delrin D25 ideal for developing, sampling and purging in 31.57mm (1.25), and
larger wells. Used with 16mm (5/8") OD tubing. Flow Rate: 0 - 6 L/min.
Lift Capacity: 40meters. |
 |
|
Standard Flow - SS-19
Use this Waterra® footvalve when Delrin is unsuitable for your sampling,
developing or purging processes.It fits easily down 31.57mm (1.25) and
larger wells. It features a self tapping female thread, durable, excellent
resistance to organics, used with standard LDPE16 or HDPE16 (5/8") OD
tubing. Flow Rate: 0 - 6 L/min. Lift Capacity: 40meters.

Standard Flow - Specialty Valves D-16 and SS16
Use these Waterra® footvalves internally with the same LDPE16 tubing. Available
in either Delrin (D-16) or Stainless Steel (SS16), they screw inside the tubing, allowing
usage in narrower wells.
This system can also be adapted for well
development by installing a SBD-25 Surge Block to the D-25 footvalve. This
device causes the pump to simultaneously surge and pump, removing fine
material from the well and well screen. |
|
|
|
 |
|
High Flow
The High Flow System is designed to be used in 2
inch wells or larger where a high pumping rate is desired. This system is
also an excellent well development tool in 2 inch piezometers. |
|
|
|
 |
|
High Flow - D32
Delrin D32 valves with 25.4mm (1) OD LDPE tubing. Ideal for: Deep well sampling, Large
diameter wells, Well development, and Sediment-laden wells. Features: Self tapping female
thread, durable, excellent resistance to organics, excellent silt handling abilities and
high flow rate. Flow Rate: 0 - 13 L/min. Lift Capacity: 42meters. |
 |
|
Low Flow
The Low Flow System is designed to be used in
small diameter piezometers (usually 1" ID to 0.75" ID). |
|
|
|
 |
|
Low Flow - D13
Use D13 with ½ OD by 3/8 ID tubing. Ideal for sampling in piezometers, sampling damaged
wells and custom installations. Flow Rate: 0 - 2.2 L/min. Lift Capacity: 20meters. |
 |
|
Low Flow
The Micro Flow System is popular for use in
direct push technology micro well installations.
|
|
|
|
|
|
|
Microflow - SS10
Use SS10 with 3/8 OD tubing for Micro wells, damaged wells, custom installations and
direct push technology. Flow Rate: 0 - 2.1 L/min. Lift Capacity: 14meters. |

Tubing
Options - Low Density & High Density Polyethylene
LDPE16
- for D25, SS19, D16, SS16
5/8 OD low density polyethylene (LDPE) softer
and easier to work with than HDPE, comes in 50m coils, 0.5m diameter
HIGHHDPE16 - for D25, SS19, D16, SS16
5/8" OD high density polyethylene (HDPE)
provides extra stiffness for deeper applications. Comes in 100m coils, 1m
diameter.
HDPE25 & LDPE25
- for D32s
1" OD comes in HDPE, 100m rolls. Rigid enough to
get to most depths. Also available LDPE25, low density polyethylene tubing
in 100m rolls. |
