The HYGHSPIN is the basic model from the worldwide tried and tested HYGHSPIN pump series made of high-quality stainless steel. Whether aqueous, highly viscous, lumpy, fibrous or gas loaded - the HYGHSPIN is suitable for flow capable products of virtually any consistency and therefore is characterised by its high efficiency. The particularly service-friendly twin screw pump impresses with a very high suction power and gently transports all flow capable products in volumes of up to 300 m³/h. An additional pump for CIP cleaning is therefore not necessary: A considerable time and cost saving due to reduced investment and maintenance costs is thereby guaranteed.

THE ADVANTAGES AT A GLANCE

Considerable cost savings
Reduced investment, maintenance and service costs
Top quality
Manufactured completely of stainless steel
Exceptionally easy to service
The pump does not have to be removed from the system for service and maintenance works
Highest flexibility
Various products, viscosities and volumes can be conveyed with just one pump
Gentle to products and uniform conveying
Low speed, minimum pulsation, no pressure impact
Highest hygiene level
No cavities and particularly good rinsing for the shaft seal
CIP and SIP
Cleaning and sterilising within the system, application as CIP-Conveying pump
