Material design
Various materials can be supplied from cast iron, bronze to high chrome steel and even rubberised materials.

Impeller design
Closed, multi vane, impeller designed to maximize efficiency and low flow pulsation.
Vortex impeller, for pumping the toughest fluids.
Semi-vortex impeller, for pumping though fluids with a better efficiency then a vortex impeller.

Sealing design
The mechanical shaft sealing is never exposed to the pump pressure, since the connection between the motor and the pump casing is open. Leakage from the pump casing is controlled by efficient sealing-vanes on the back of the impeller. The oil-chamber between the seals provides a buffer against the surrounding medium, and it is fitted with a leakage monitor to warn against water penetration. The motor is also fitted with temperature monitors and a leakage probe for the stator housing.

Motor design
Standard version has there own developed high efficiency motors. Upon request the pump can be executed with an other make motor and/or an ATEX certified motor. 

Markets
The pumps are designed for pumping abrasive suspensions such as pulp, slurries, mill scale, industrial effluents and drainage from mine galleries and tunnels. The pumps are commonly used in sand dredging and floor cleaning applications. Customers for DELTA ODH heavy duty slurry system include the mining industry, steelworks and the construction industry, but it can be used wherever there is a need to pump abrasive suspensions. Continuous operation is recommended, especially when pumping coarse and fast settling solid particles.
