We offer a complete range of liquid transfer pumps and air compressors designed for safe, fast and efficient unloading of bulk liquids from road tankers. Our systems support many types of liquid products, including food ingredients, chemicals, fuels, oils, hot bitumen, resins and liquid waste. Whether your operation needs compact equipment, high performance or flexible installation options, we can provide the right pump for liquid transfer to match your daily work.
Using proven technologies, our equipment helps operators unload faster, save fuel and maintain reliable performance across different applications. Every solution is built with durability, safety and ease of use in mind.
Our liquid transfer range includes:
Each system is designed to shorten unloading times, reduce operating costs and provide long‑term reliability. Our equipment supports many types of liquids, from thin food products to thick chemicals and challenging waste materials, ensuring you always have the correct pump for liquid transfer.
Below are three simple comparison cards to help customers understand the differences between compressors, vacuum pumps and stationary pumps.
Fast Discharge of Low‑Viscosity Liquids
Provide high airflow to quickly unload thin liquids.
Fast unloading ✦ Compact & lightweight ✦ Low noise ✦ Lower fuel use ✦ Wide product compatibility
The compressor pressurises the tanker, pushing liquid out smoothly and efficiently.
Food liquids, oils, fuels, solvents and other low‑viscosity products.
GD150 / GD175 • SC200 • WITTIG SLS‑54
Strong Suction for Waste Liquid Collection
Vacuum pumps create deep suction so waste liquids can be drawn into the tank from pits, drains and collection points.
Powerful suction ✦ Low noise ✦ Compact footprint ✦ Efficient cooling ✦ Wet & dry waste options
By removing air from the tank, the system pulls liquid upward and into the tanker.
Wastewater, sewage, environmental liquids and jetting/vacuum combination tankers.
WITTIG RFW • WITTIG RFL102 • Aqualine • WITTIG SLS‑54
Gentle, Low‑Shear Pumping for Sensitive Liquids
Stationary rotary lobe pumps move liquid smoothly and gently, ideal for industries where product integrity matters.
Low‑shear pumping ✦ Energy‑efficient ✦ Easy maintenance ✦ Hygienic design ✦ Handles high viscosity
Rotating lobes transfer liquid forward with minimal agitation and controlled flow.
Food, beverage, chemical, pharmaceutical and high‑viscosity liquids.
SX • SRU • Optilobe • Series A • Series M • Series N
Compressors are one of the fastest ways to unload low‑viscosity liquids. With no product‑compatibility concerns, they work across most common tanker applications. Our compressors are reliable, compact and engineered for quick and quiet discharge.
Our vacuum pumps create deep suction inside the tanker by removing air from the tank. This allows waste liquids to be drawn from pits, drains or sewage collection points. The systems provide high performance, strong cooling, low noise and a compact footprint — ideal for a wide range of waste applications. Some models are also suitable for dry waste.
Our stationary SSP rotary lobe pumps offer smooth, low‑shear pumping for liquids that require gentle handling. These pumps are ideal for food, chemical and industrial applications where product integrity and hygiene matter. They support a wide range of viscosities and offer low lifecycle costs thanks to their energy‑efficient design.
Whether you handle food liquids, chemicals, oils, fuels or waste, we can help you choose the ideal liquid transfer pump for your operation. Our technical team is ready to guide you based on your tanker setup, application and performance needs.
