These hydrostatic test pumps are quick and reliable pressure test plumbing machines, excellent for testing leakage and integrity. They are fully tested, serviced and ready for use. These units pressure test the integrity of pipes and plumbing as required by local codes.
The user is able to pump water into a closed pipeline system (hydrostatic testing), set and lock the pressure, and test to see if there are any leaks in the pipeline system. Hydrostatic test pumps are ideal for city maintenance, contractors or rental yards.

DP Diaphragm series
The Diaphragm series hydrostatic line tester pumps are large volume, medium pressure test pumps, with flow rates up to 56 GPM, and pressures ranging to 600 PSI, designed to test large diameter water lines up to 96". EXCLUSIVE, to this triple diaphragm pump is technology where
pressure is spread across the entire
face of the diaphragm virtually
eliminating torn, damaged diaphragms. Another design upgrade is the inlet suction diaphragm assembly,
eliminating the concern for ruptured
diaphragms caused by pressure
feeding, is now a separate assembly
from the pump, which can be added at
any time.

for the handling of up to a 10 chlorine
solution, and the ability to be run dry
without damaging the pump. A large
volume, medium pressure test pump,
this unit is recommended for testing up
to 24” diameter lines.
Features:
- Pressures up to 550 PSI, Flow rates up to 56 GPM
- Handles up to a 10% Chlorine Solution and can be Run Dry

Fire Hose Anchor
The Line Cage is a new, patent pending, safety secure and anchoring device for use in fire hose testing. The Line Cage was designed by a Fire Captain, with the safety and well being of his fellow firefighting brothers in mind. Manufactured with high volume at low pressure to fill the lines, and low volume at high pressure to test, eliminating the cause of an uncontrollable wild line from rupture or failure during testing.
NOTE: Meets NFPA 1962 5-5.2.3 requirements of "Securing and Anchoring" the fire hose while being tested.

| Customize your Hydrostatic Test Pump with Accessories |
 |
Some of the hydrostatic test pumps above can be customized with accessories to increase the value and use of your unit. Wheel and Handle Kits make portability a breeze, while saving time and minimizing liability costs due to improper lifting. Pressure Feed Tanks eliminate the need for hauling a 55-gallon drum from test site to test site. Pressure Feed Tanks save time, labor, repair, and maintenance costs.
Features:
- Simple and "Fool Proof" - describes the unique pressure feed tank accessories. This heavy duty polypropylene tank allows the pressure feeding of diaphragm pumps, normally requiring suction or gravity feed only. There is an on/off float valve for water level control, and a chemical additive opening on the top of the tank for easy chlorination or other chemical treatment of the test environment. All diaphragm models are tank ready and this accessory can be added at any time!
- Portable "Back Saver" - the wheel and handle kit instantly makes your test pump truly portable and easy to maneuver, saving you time, labor, maintenance, and repair. The new "NO FLAT" tires are made of polyurethane foam with open and closed air cells, creating a tire 2 times stronger than rubber, yet soft enough to provide bounce and absorb vibration.

GFCI Cords and Plugs
From: $63.75
GFCI's protect people and equipment by interrupting potentially lethal ground circuits exceeding 6mA. The dangers of electrical shocks have been long known - GFCI's are the only real way to be safe. Most city & county codes now require GFCI protection on power cleaning equipment.
Consumers should not use "adapter plugs" to connect the three-wire plug to a two-prong household receptacle without properly grounding the adapter plug. Learn more about ground fault current interupters. |
