The CSP series of chemical slurry pumps are special single-stage, normal-primed centrifugal pumps designed for use in the chemical, petrochemical, and general industrial sectors. They are characterized by standardized dimensions based on ISO 2858. Our series covers the full spectrum, ranging from simple basic models to variants compliant with ISO 5199 and those based on API 610-OH1. The scope of supply ranges from individual pumps with free shaft ends to fully developed, highly integrated complete systems.

The primary application of chemical sewage pumps is the pumping of a wide variety of contaminated or solids-laden liquids generated in process engineering plants. Due to the available material options, our pumps are ideally suited for pumping aggressive or abrasive liquids. Contaminated acids, bases, or slightly viscous media can also be handled by these pumps.

• Conveying of process liquids

• Production of biofuels

• Chemical recycling of plastic waste

• Industry and plant engineering

• Circulation of liquids

• Rafinery and offshore applications

The use of vortex impellers or channel impellers, as used in wastewater technology, makes this pump ideal for handling demanding fluids. Crystalline, solids-laden, or particle-laden liquids can be pumped dependably, without blockages and with minimal wear. Depending on the pump and impeller design, the free passages can be up to 90% of the discharge outlet nominal diameter—a decisive advantage when pumping media loaded with solid particles.

The selection of seals and materials is identical to our established CNP series of chemical standard pumps. Furthermore, the robust bearings of the CSP series are identical to those of the CNP series, ensuring high operational reliability. The use of standard parts allows for easy replacement of spare parts, significantly reducing storage and maintenance costs.

Existing systems with a standard chemical pump can be easily upgraded to the CSP series chemical wastewater pump without complex modifications, thanks to ISO 2858-compliant connection dimensions. This upgrade allows safe operation with abrasive and solids-laden media and provides a significantly longer service life compared to conventional standard chemical pumps.
