N - Standard Progressive Cavity Pumps

The universal basis

The N module forms the robust basis for all SEEPEX progressive cavity pumps. It can pump low-viscosity to viscous media, with and without solids, and can be used in virtually all industries - from the environmental industry to the chemical industry and food production. The pumps are fitted with round flanged suction and pressure connections, as well as large spherical inlet openings for the simple intake of media that contain solids.

Features and Benefits

Low pulsation

Steady, even delivery thanks to low pulsation, without separate dampeners or compensators

Gentle

Low shear thanks to low speed - ideal for pumping sensitive media

Flexible installation options

Depending on the on-site conditions, installation is possible in a horizontal or vertical position with a large, rotatable, spherical suction intake

Compatible

Available with various rotor/stator geometries and a wide range of different shaft seals – tailored to suit any conveying process

Powerful suction

Strong suction forces for easy transport of viscous media as well as air or gas-liquid mixtures with a water column of up to 9m
