Hydrant Surge Control
Stop water hammer inside the hydrant.
Every hydrant opened or closed too quickly fires a surge wave straight into your distribution main. PulseTech builds a drop-in replacement valve plate that absorbs it at the seat — inside the shoe, before it ever reaches the main.
- Drop-in retrofit
- Fits standard dry-barrel hydrants
- No excavation
The Name Reflects our Mission
Our name, PulseTech, reflects our commitment to taming the pressure pulse — protecting the pipes, valves, and equipment behind every building with engineered surge arrestors.
When a valve snaps shut, water moving through a pipe stops in milliseconds — and the resulting shockwave can spike to more than 10 times the system’s normal operating pressure.

● The Force We Control
Water is heavy, fast, and unforgiving. Managing its momentum is what we do.
Perfecting
Proven Physics
Our arrestors modernize the sealed-piston air chamber — a principle trusted for over a century — with precision-machined stainless vessels, permanently lubricated seals, and factory-charged air cushions that never waterlog, absorbing pressure spikes of up to 400 PSI.

● Design Meets Resilience
Every PT Series arrestor is engineered, tested, and certified to absorb hydraulic shock for the life of the system it protects — completely maintenance-free.
The Part We Make
The surge starts at the seat. Close a hydrant too fast and the valve plate slams against the gasket, sending a pressure wave down the shoe and into your distribution main. Our replacement plate absorbs that closure instead of passing it on.

Routine Flushing
Unidirectional flushing and hydrant exercising are the most frequent surge events on a distribution system — and the ones crews repeat hundreds of times a year
Main Breaks
Repeated pressure transients fatigue cast and ductile iron mains, opening joints and propagating cracks years before the break shows at the surface

Fire Flow & Testing
Flow tests and fire-ground operations close hydrants fast and under pressure, which is exactly the condition that drives the sharpest transients
Services & Meters
The same wave that stresses the main travels into service lines, loosening joints and shortening the life of meters and customer plumbing

Unmatched
Surge Suppression
In the milliseconds after a fast-closing valve shuts, an unprotected system can spike past 400 PSI. Our PT Series holds that transient to within a few PSI of static pressure — every cycle, for decades.
Stopping Hydraulic Shock
Everywhere Water Moves
Together, these capabilities protect critical systems across key sectors — commercial towers, fire protection, healthcare, industrial process, and municipal networks.
Protection
as a System
A single arrestor solves a noisy fixture. An engineered layout protects an entire network.
Our engineering team models your riser diagrams, fixture counts, and pump curves to size and place arrestors across the whole distribution system — from the meter to the last branch line.
