The universal solution for diverse pumped media

Whether aqueous, highly viscous, lumpy, fibrous, corrosive, abrasive or gas-laden – the CHEMSPIN series of high-grade stainless steel pumps is suitable for media of virtually any consistency, thereby featuring utmost efficiency.

The particularly service-friendly twin screw pump convinces with a very high suction capacity and gentle conveyance of all products. Self-priming, and able to handle entrained gas, they ensure fast and safe medium transfer. For non-free flowing media, use of the CHEMSPIN ES is recommended.

Herausforderung: Entgasen von Säften mit Fasern und Pulpen in der Getränkeindustrie

An important advantage of all CHEMSPIN pump versions is their versatility. They enable the most varied pumping and rinsing operations to be handled by the same pump. Consequently, the range of different pumps within a plant is greatly reduced. There are no additional investments, and maintenance costs are cut dramatically.

This combination of features is unique. As a positive displacement pump, the CHEMSPIN is also suitable for high viscosities. Hereby, pump throughput is not pulsating, but almost as smooth as that of a centrifugal pump. Suction capability and the multi-phase ability are comparable with those of a side channel pump – the CHEMSPIN can also pump media with solids content.

The CHEMSPIN has a modular design and is available in all sizes – with free shaft end in sizes 70, 90 and 125. Delivery pressure is up to 35 bar with single-flow, and up to 50 bar with double-flow pumps.

The advantages

Very high flexibility
Many different products and a wide range of flow quantities and viscosities can be handled by a single pump. Reverse operation is possible – the range of different pumps in a plant can be reduced considerably.
Safe operation
Loaded, abrasive or lumpy media can be conveyed – a suitable shaft seal can provide dry-run protection. Very low vibration and noise levels.
Low cavitation risk
The CHEMSPIN exhibits very low NSPH values. This applies for the full operating range, also for operating points close to zero throughput. Increasing pump speeds and viscosities only have a limited effect.
Self-priming, able to handle entrained gas
Outstanding suitability for emptying & transfer pumping operations.
High chemical resistance
The CHEMSPIN is made of 1.4404 stainless steel as standard. Hardened pumping elements and contactless operation ensure high wear resistance.

Consequently, the CHEMSPIN ES represents a very attractive 3-in-1 solution: Infeed, conveying, and cleaning are carried out in a single unit. It is available in the sizes 70, 90 and 125.
