Zurn Wilkins 975XLHBM Fire Hydrant Backflow Meter Combination

Zurn Wilkins 975XLHBM Fire Hydrant Backflow Meter Combination

Product Overview

The Zurn Wilkins 975XLHBM Hydrant Backflow Meter Assembly combines a Reduced Pressure Zone (RPZ) backflow preventer with a Class II turbine water meter to provide both backflow protection and accurate water measurement from temporary water sources such as hydrants. Designed for potable water applications, it safeguards against both backsiphonage and backpressure while recording water usage in non-permanent setups.

Built with a bronze body, anodized aluminum meter, and brass connections, the 975XLHBM is engineered for reliability, portability, and ease of use in demanding field applications.

Features & Benefits

• Dual Protection: RPZ assembly prevents contaminated water from flowing back into the potable supply.

• Integrated Metering: Class II turbine water meter provides accurate usage measurement.

• Portable & Durable: Lightweight anodized aluminum meter and bronze valve body designed for temporary hydrant connections.

• Quick Installation: 2-1/2" NH (NST) adapters with swivel fittings enable fast setup.

• Easy Maintenance: Check valve access covers allow servicing without removing the entire assembly.

• Flow Control: Outlet shutoff valve enables simple adjustment of flow on-site.

• Enhanced Accuracy: Straightening vanes minimize turbulence for precise readings.

• Extra Protection: Inlet screen prevents meter damage from debris.

• Convenient Handling: Built-in lifting handles and adjustable support stand for quick, stable installation.
