Specifications
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
Impeller:
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.
Priming:
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).
Bearings:
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.
