Gusher Pumps
Gusher Pumps by Ruthman Companies is a brand present in many industries across the globe, with their centrifugal pumps at the centre of their offerings. Operating since 1913, Gusher is the inventor of the vertical sealless pump technology. Currently, the manufacturer designs reliable and long-lasting close-coupled pumps, immersed pumps, multi-stage pumps, end suction pumps, self-priming pumps, sludge pumps, complete cantilever pumps, and vortex pumps in either vertical or horizontal orientation.
Their pumps also come in different sizes to suit many head ranges without the need to downsize or upsize a system’s operating characteristics.
8000 SERIES CENTRIFUGAL SELF-PRIMING PUMPS
Gusher Pumps’ 8000 Series is engineered for various agricultural and industrial applications, including filtration, irrigation, dewatering, transfer, industrial sump, shallow sump washers, and tank car unloading. The range features self-priming, horizontal centrifugal pumps that use semi-open impellers and can have an external impeller adjustment. Maintenance in these pumps is more straightforward than in other types without external valves, air separators, or priming chambers.
Furthermore, the back pull-out design makes servicing a Gusher 8000 pump easier than ever. They also feature clean-out ports for the faster removal of foreign materials.

Principle of Operation
The working principle of centrifugal pumps involves imparting energy to the liquid using a centrifugal force developed by rotating an impeller with several blades or vanes. Fluid enters the pump casing at the impeller eye. Velocity energy is then imparted to the liquid using the centrifugal force produced by the rotation of the impeller, and the fluid is radially pushed out towards the impeller periphery. Finally, the velocity energy of the liquid is converted to pressure energy by directing it to an expanding volute design casing in a volute-type centrifugal pump or diffusers in a turbine pump.
7071 SERIES HORIZONTAL END CENTRIFUGAL SUCTION
Gusher Pumps’ ANSI 7071 centrifugal pumps meet the ANSI B73.1 standards, allowing users to switch brands without affecting the piping location, coupling, motor attachment, or bedplate dimensions. These end-suction pumps are available in a wide range of materials. They can handle various fluids, making them useful in chemical, refineries, food manufacturing, oil, pulp & paper, pharmaceutical, and other process industries.
The ANSI 7071 pumps are easy to operate and energy savers, helping owners reduce operational costs.

Principle of Operation
VERTICAL HEAVY-DUTY PUMPS
Gusher Pumps boasts a range of powerful pumps through its 7550 and 7600 Series. These vertical centrifugal pumps offer heavy-duty pumping services in various applications. They are economical to use since they remove the need for a seal which is a common wear part in centrifugal pumps. Their solid construction allows for long-lasting operation. These pumps are also easy to service, with the 7600 Series’ top pull-out design enabling the easy removal of the rotating element without touching the piping and mounting plate.
Overall, these attributes contribute to a system’s minimised downtime.
Features & Benefits
- Automatic pump to motor alignment
- Semi-open impeller with back pump-out vane
- Eliminates problems with cavitation and air entrainment
- Non-contacting carbon throttle bushing for minimised wear
