The Axiflow Technologies DF High Pressure Series of pumps consists of (2) primary pump sizes with up to three (3) different screw pitches to customize an engineered solution
Capable of discharge pressures up to 725 PSI (differential), the DF Series pumps are ideal for large high pressure drop pasteurizers. Until now, whenever a process called for a positive displacement pump capable of pressure above 300 PSI, the only option processors have had was to use a homogenizer without a homogenizing valve. This type of equipment has a large footprint, is expensive and is very maintenance intensive. Additionally, these pumps typically cause tremendous pulsation.
The Axiflow DF High Pressure pumps provide a smooth, non-pulsing flow and are a fraction of the upfront and maintenance costs.
STS Standard Pump Curves
The enemy of the homogenizer is air! This can cause severe damage and drastically increase maintenance costs. The same twin screw technology that enables you to pump up to 60% air on the Axiflow STS Standard Series pumps allows the high pressure series pumps to convey the air through the pump without damage. Designed with a double mechanical seal with a flush, these pumps are also capable of running dry for extended periods of time.
With an all stainless steel wet end and bearing housing that is machined completely out of 316L billet stainless steel, the Axiflow pump can handle the widest range of temperature swings. With the Axiflow pump, there is no such thing as “hot clearance” and “cold clearance” rotors. The entire pump expands and contracts together.
Just Like the Standard Series Pumps…
The DF High Pressure Series pumps come standard with an all stainless steel wet end and bearing housing that is machined completely out of 316L billet stainless steel. They can also run at speeds up to 3,000 RPMs. This means that they can perform process as well as CIP—just like the standard series Axiflow pumps.
