Waterous S200 Passport

The S200 fire pump was designed by Waterous engineers to provide the utmost quality and reliability that comes with the Waterous name. With the goal of reaching international standards, the S200 accomplished that goal by meeting EN 1028, NFPA 1901 (North America) and CCC in China. The S200 is quieter, lighter and more flexible than any other fire pump on the market today. You can rest assured that the dependability and quality of the S200 is guaranteed by a 5-Year Limited Warranty.


Key Factors:

  • Maintenance-free (oil-free primer and self-lubricated bearings)
  • Built-in automatic primers
  • Weighs less than 200 lbs. (91 kg).

Volute Body and Head:

Bronze with lightweight composite materials


Bronze impellers are standard

Impeller Shaft:

Consists of an impeller mounted on a stainless steel shaft with selflubricated sealed bearings.

Shaft Seal:

The mechanical seal consists of a flat, highly polished (lapped), selfadjusting (spring-fed) carbon ring that is sealed in the pump body. The carbon ring presses against a highly-polished rotating ring that is sealed to and rotates with the impeller. Mechanical seal is retained in and easily removable seal housing.

Pedestal (Primer Housing):

The pedestal is constructed of anodized aluminum and supports the piston primers and main bearings. Contains no oil. Maintenance is not required.


Integrated, fully automatic, oil and maintenance-free piston primer with 50% more capacity than a typical piston primer. All components are constructed of corrosion-resistant materials.

Thermal Relief Valve:

The thermal relief valve opens as the temperature of the water inside the pump reaches 49° C. The valve opens and diverts water to one of the following locations:

  • To the holding tank, vehicle tank or to atmosphere (ground).


The main pump shaft uses long-life, double-row angular contact ball bearing and a single-row ball bearing that are self-lubricated, doublesealed and require no maintenance.
