Unloading refers to the transferring liquids between “modes” of travel, be it from refinery to terminal, terminal to supplier, supplier to storage facility, or supplier to end-user. The products that are typically transloaded can range from liquid chemicals and petroleum products, animal fats, vegetable oils, to raw and semi-finished ingredients. The modes of travel include marine, pipeline, rail, air and truck. Goods, whether raw or finished, rarely ever travel directly from their source to the end-user. In essence this area concerns offloading pumps and loading pumps.
AxFlow offer a number of rotary lobe pump ranges that are often used as offloading viscous liquids and ingredients. Our process pump range allows us to handle high flows, corrosive and toxic liquids, food and pharmaceutical products, combustible fluids and liquified gases.

Centrifugal Unloading Pumps 
Self-priming centrifugal pumps are often used in offloading applications where a relatively high flow is required and when the pump is positioned above the vehicle or vessel being offloaded. Click the icon below for more about our range of Self-priming Centrifugal Pumps
- AxFlow offers 6 ranges of iso 5199 pumps giving us the ability to cater for most liquid types found in chemical processes. We also offer API 610 and API 685 units if the flows dictate this.
- For higher flows of up to 3500m3/hr AxFlow offer both horizontal and vertical split case double suction pumps.
- Canned Pumps are often used for offloading liquified gases and can be configured with these applications in mind.
AODD Unloading Pumps 
If compressed air is available AODD pumps are an excellent all round pumps for smaller offloading duties as they are self-priming, can handle solids, are chemically resistant, can be hygienic, ATEX rated and can clear the line.

Hose Unloading Pumps 
Hose pumps offer most of the same benefits of an AODD pump but without the need for compressed air. Click here for more about our range of Peristaltic pumps
Eccentric Unloading Disc Pumps 
Eccentric Disc pumps are particularly useful as offloading pumps as they can be hygienic, have a gentle pumping action, are self priming, can run in reverse and will clear the line of liquid. Click the icon below for more about our range of Eccentric Disc Pumps.
Vane Unloading Pumps 
Sliding vane pumps are self-priming, designed to run dry for short periods, and their high suction capability makes them ideal for suction line-stripping. They are ideal for offloading applications or loading applications where higher flows are required but with a need for self priming. Click the icon below for more about our Rotary Vane Pumps.
Rotary Lobe Unloading Pumps 
Our portfolio includes rubber lined models, hygienic lobe pumps and Waukesha external circumferential piston pumps that can cope with viscosities of up to 1 million cP.
