Hydraulic Submersible Pumps
Features
Submersed Pump Head

With the pump head being submersed in the water it is pumping, suction lift limitations no longer exist.

Biodegradable Lubricants

Pump head hydraulic lubricant fluids are biodegradable and used with the environment in mind.

Triple Hose Design

Three hoses connect the pump head to the power unit: high pressure, low pressure, and bypass.

Trash Type Strainer

Corrosion-resistant and durable strainer retains pump function versus sludge, muddy water, sewage, and more.
