ESU1C22

Get the power and performance of a traditional full-body fire pump in a compact, lightweight design. Available as a direct-driven pump or matched with a Waterous split-shaft aluminum-case transmission.

The ESU1 Split-Shaft model is equipped with a chain-driven C22 Transmission. The C22 Transmission provides the best In-Class power transfer. The silent chain-drive provides no gear whining, provides positive shifting and requires less horsepower that will enhance the efficiency of the apparatus.

Options and Accessories

Priming System: An electric, oil-free rotary vane primer or air activated primer mounted directly on a Waterous split-shaft pump transmission or separately mounted combined with a Waterous priming valve forms the priming system. A lubrication option allows the use of Prime-Safe lubricant (priming tank is required when the lubrication option is selected).
Pressure Control System: The Waterous Intake Relief Valve system is designed to act as a safety valve by “dumping” excess pressure from the inlet side of the pump. The Discharge Relief Valve provides sensitive pump control to protect firefighters from sudden pressure surges resulting from changes in discharge flows from the pump.
Manifold Drain Valve drains all points of the pump simultaneously with the operation of a single control.
Corrosion Protection: Replaceable magnesium element that is installed directly on the pump intake piping and into the pump waterway. These anodes sacrifice the magnesium element to galvanic corrosion.
Discharge Valves: Your choice of the trusted Waterous 1⁄4 turn 2.5 inch and 3.5 inch rack and sector push-pull, worm gear and electric discharge valves. All come standard with chrome-plated brass ball and hydraulically balanced seal assembly.
Overheat Protection Manager: The OPM consists of an illuminated warning light on the operator’s panel whenever the pump approaches an overheat condition. Optional audible alarm is available.
Power Shift (C22 Transmission): Pneumatic shift allows operator to shift from ROAD to PUMP position by actuating a valve.
Electronic Tachometer Sensor (C22 Transmission): Monitors driveline rotational speed.
Waterous 21st Century Manifold: Designed to be mounted on the discharge flange and can be oriented for top or side-mount control panels.
Seven-Year Limited Warranty with Total Protection Package (TPP-5): The Total Protection Package is a comprehensive warranty that increases your standard 7 year warranty to include labor expenses to dismantle, remove and reinstall covered products or parts for a period of five years.
