Water Hammer Arrestor

Product Overview

A water hammer arrestor is a device installed in plumbing systems to absorb pressure surges caused by sudden changes in water flow, thereby preventing the phenomenon known as "water hammer" that can damage pipes and fixtures.

Working Principle

The device typically consists of a steel shell and a flexible rubber bladder. Under normal conditions, the air and water inside the tank are balanced. When negative pressure occurs in the pipeline, water from the tank is quickly injected into the pipeline under the pressure of the compressed air, preventing collapse. Conversely, when pressure surges occur, water enters the tank, mitigating the pressure spike and protecting the system.

Product Features

Corrosion Resistance: The medium does not directly contact the tank body, preventing rust.

Hygienic Safety: The bladder is made of rubber materials that meet drinking water standards, ensuring water quality.

Easy Operation: Air is stored between the bladder and the tank body, reducing leakage risk and eliminating the need for frequent air charging.

Safe and Reliable: Provides supplementary pressure during negative pressure events and absorbs pressure during water hammer incidents, preventing system damage.

Simple Structure: Designed for high reliability with minimal maintenance requirements.

Durable and Stable: The rubber bladder is corrosion-resistant and wear-resistant, offering a long service life; the tank body can be used for an extended period.

Application Scenarios

Widely used in water supply systems, pump stations, high-rise buildings, and industrial pipelines, especially in systems requiring frequent pump starts/stops or rapid valve operations. Installing a water hammer arrestor effectively prevents water hammer phenomena, ensuring stable system operation.

Selection & Installation Recommendations

Selecting an appropriate water hammer arrestor requires considering factors such as system working pressure, flow rate, and pipeline size. Installation should follow design drawings, ensuring secure connections between the tank and pipeline, and adjusting pre-charged pressure based on actual operating conditions to achieve optimal protection.
