Axiflow - North America’s Leader in
Sanitary Twin Screw Pumps
Spotlight: Axi-Auger Modified Twin Screw Pump
Our new product has all the features of our standard twin screw pump, but it adds a modified front end utilizing a hopper style opening. All the capabilities are the same, but now we can stuff the pump with higher viscosity products. This solution expands our broad spread of applications to feature even more.
STS Series Twin Screw Pump
Whether your needs call for timing product through a high pressure drop pasteurizer, stuffing a homogenizer with a high viscosity liquid, or simply transferring a shear sensitive slurry or emulsion, Axiflow Technologies offers the widest range of pumping solutions for the sanitary industry.
Hopper Pumps
Highly viscous products like cake frosting and cold peanut butter that do not flow are a challenge for any pump. Other products that consist of a water-like liquid base with large soft solids can bridge and cause de-watering while pumping and then end up damaging the delicate solids.
Our “open-throat” hopper design for light liquid based products, adds to Axiflow’s wide range of solutions for the sanitary industry.
High Pressure Pumps
The Axiflow Technologies DF High Pressure Series is 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 high pressure positive displacement pump, the only option processors had was to use a piston style pump. This type of equipment has a large footprint, is expensive, and is very maintenance intensive. Additionally, these pumps can cause significant pulsation.
The Axiflow DF High Pressure pumps provide a smooth, non-pulsing flow and are a fraction of the upfront and maintenance costs.
The Axiflow Technologies STS Standard Series of pumps consists of four (4) primary pump sizes. Axiflow pumps have a variety of screw pitches which gives you the flexibility to customize each pump specifically for your application. The smallest STSC50 size is only available is a C-face connection. The STS70, STS90, and STS125 are available in both C-faced connection or bare shaft with coupling.
STSC 50 (C-Face) Suction/Discharge Connections – 1 ½” to 3”
STS 70 Suction/Discharge Connections – 2” to 3”
STSC 70 (C-Face) (Not Shown) Suction/Discharge Connections – 2” to 3”
STS 90 Suction/Discharge Connections – 2 ½” to 4”
STSC 90 (C-Face) (Not Shown) Suction/Discharge Connections – 2 ½” to 4”
STS 125 Suction/Discharge Connections – 3” to 8”
STS 125 (C-Face) Suction/Discharge Connections – 3” to 8”
All standard series pumps are available in standard 3A and EHEDG design as well as aseptic design. Pressure ratings on the standard series pumps range up to 525 PSI differential depending upon screw pitch and pump size.
Axiflow Technologies offers a c-face motor connection for most pump designs and sizes. This makes the motor self-aligning and gives you a smaller footprint.
STS Standard Flow Rates & Pump Curves
Flexibility Saves You Money!
The Axiflow Twin Screw design enables the pump to run at the widest range of speeds of any other positive displacement pump on the market. This capability enables one pump to be sized to handle a wide range of viscosities. Imagine one pump handling the duty of many!
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.
Screw Pitches
With each pump size we offer a wide range of screw pitches. The screw pitch is the distance from flank to flank. With smaller screw pitches we can handle higher pressures. With larger screw pitches, we can achieve higher flow rates and delicately handle larger soft solids.
Pump Speeds
The most unique aspect of the Axiflow Twin Screw pumps is that they can
run at speeds up to 4,000 RPMs. Typical rotary lobe, circumferential piston
and progressive cavity pumps are more limited. This ability to run at such a wide range of speeds enables The Axiflow Pump to perform process, as well as CIP.
With high suction capability, the ability to run dry for long periods, low shear pumping capability, delicate handling of soft solids up to 2-5/8” and the ability to deliver a smooth, non-pulsing, repeatable product flow, the Axiflow Pump is capable of pumping a wide range of product viscosities (1 to 2,000,000 cps), operating at speeds up to 4,000 RPM, and product temperatures up to 425°F! These capabilities greatly reduce the wear on the pump and need of spare parts.
