Included in our portfolio of industrial cleaning equipment is a range of high specification Vacuum Transfer Equipment.
Specifically designed and custom-built, the equipment is fully certified for use in Zone 2 (Offshore classified) hazardous areas for the uplift and transportation of waste materials (for example, dry powders, sand, sludge and slurries) from tanks and vessels.
Environmentally Sensitive and Safe
This innovative, safe and ergonomic development minimises the need for entry into tanks or vessels to carry out cleaning. Whilst the application of this technology does not always provide the complete solution, it can significantly reduce the man-hours needed in the vessel and therefore reduces the possibility of hazard and risk exposure. Our ‘brain over brawn’ philosophy proves that enhanced safety and productivity can be simultaneously achieved.
The environmental benefits of the vacuum transfer system include:
- Emission-compliant engines
- Integral bunds
- Noise suppression and enhanced atmospheric protection
- HEPA filtration option to remove contaminants from expelled air during transfer operations

Waste Material Transfer Solutions – Hydraulic Pumping
To complement our extensive range of Vacuum Transfer Systems and traditional pneumatic pumping solutions, we also operate a range of Hydraulic and Pneumatic Pumping Solutions from our equipment inventory.
Hydraulic Driven ATEX approved Rotary Lobe Pumps which are designed for bulk material transfer. Of a compact design suitable and detachable from transit frame for entry into a standard man way, they are completely reversible and are capable of pumping materials with SG of up to 2 to a height of 50 metres at a flow of up to 10m3 per hour.
The Lobe Pumps can be used in tandem with Vacuum Transfer equipment as well as being a viable alternative when vacuum transfer is not the ideal solution. The addition of the Lobe Pumps provides both Sureclean and by extension, our clients, with enhanced material transfer solutions.
Archimedes Screw Pumps for Sludge Transfer Operations
We have added Hydraulic Driven Archimedes Screw Pumps to our armoury as an addition to the range of Hydraulic pumps designed for bulk material transfer. The compact design is suited for deployment through man ways down to 0.4m diameter. Relatively lightweight with maximum flow rate of 30m3 per hour and a maximum discharge pressure of 10bar. Powered by a Zone II Hydraulic Power Pack the Archimedes Screw Pump give added versatility to the pumping systems required for particularly difficult sludge transfer operations.
The Screw Pump can be used as an alternative to the Lobe Pump for transfer of viscous materials, adding an extra dimension to the suite of pumping capabilities.
Our jet pumps rely on a Venturi effect to create a secondary flow, have no moving parts but achieves its purpose by employing specially designed venturi nozzles to convert high pressure water energy to velocity and back again. We have a number of pumps available to suit a range of different applications.
Diaphragm Pumps (Pneumatic)
We have a range of air operated diaphragm pumps ranging in sizes to optimise and provide variable flow rates. Amongst our fleet we have aluminum, stainless steel, cast and polypropylene options which allow us to pump a diverse range of chemicals and materials.
A centrifugal pump is a rotodynamic pump that uses a rotating impellar to increase the velocity of a fluid. With both diesel and electrical options available our centrifugal pumps are commonly used to move liquids and slurries through a piping system. Skid mounted and powered by an electric motor the pumps have an optimum flow rate of 180m3/hr.

Vacuum Systems with HEPA Filtration
Specifically designed and custom built our fleet of Vacuum Systems are fully certified for use in Zone II hazardous areas and provides an innovative, safe and ergonomic solution to the controlled movement of a broad range of waste materials including dry powders, sand, sludge and slurries.
How it Works
Material at source is drawn through flexible anti-static and earth bonded hose assemblies and deposited in a vacuum rated waste skip. Air continues to flow from the skip to the filtration hopper where any airborne particles are retained by the filter elements. Finally, air enters the vacuum pump inlet via the sludge filter and 4-way control valve. Outlet air from the pump carries a high precipitation of water that is mostly removed in the water separator tank. Air exhausting from the separator tank passes through a vortex shedding flow metre before entering the water separator filter where any remaining moisture is removed. Exhaust air from the separator either vents to atmosphere or is filtered.
The environmental benefits of the vacuum transfer system include:
- – Emission-compliant engines
- – Integral bunds
- – Noise suppression and enhanced atmospheric protection
- – HEPA Filtration option to remove contaminants from expelled air during transfer operations
A building block approach provides options for the correct combination of constituent parts for specific work-scopes. For easy deployment and handling, every item is individually designed to be robust and compact.
Material Dependant Productivity
Volume removal figures are very much dependent on the types of transportable material. Typical removal rates of 8–12 m3/hr are routinely achievable.
Vacuum Transfer Unit
The heart of the transfer system, it typically comprises of a liquid ring vacuum pump, diesel engine, sludge filter and high capacity water filter all housed within a self bunded, acoustically lined container. Although electrical and hydraulic options are available. Specifically configured to enable continuous transfer of material. Airflows in excess of 3550m3/hr (2200 cfm) ensure effective conveyance of viscous or heavy media over long distances and high vertical lifts, although electric and hydraulic options are also available.
Continuous Feed Discharge Hopper
The continual feed discharge hopper provides additional waste handling options. A skid unit, certified for hazardous areas, houses a 4000 litre collection tank for direct connection to the vacuum source.
The vacuum filter is an inline component of the filtration pack that can be connected downstream from the vacuum suction head and vacuum waste containers. The filter can be used to reduce the level of dust carry over during the transport of dry materials.
HEPA Filter Unit
The High Efficiency Particulate Arrestance (HEPA) filter pack is used where an extremely high level of cleanliness or purity is required. Particularly effective in negating potential problems which could arise from the presence of hazardous particulates or physiological problems caused by viable airborne organisms.

Vacuum Systems for Waste Transfer – Technical Specification
The design and construction of our Vacuum Transfer Equipment allows for controlled movement of a diverse range of waste liquids, sludges and solid materials in a safe and efficient manner.
The five main components of the system are:
- – Vacuum Transfer Unit
- – Vacuum Filter Unit
- – HEPA Filter Unit
- – Vacuum Discharge Hopper
- – Vacuum Skip(s)
Vacuum Transfer Unit
Typically a self-bunded, acoustically lined, containerised, diesel driven vacuum pump with a water separator and a sludge filter. Electric and Hydraulic options are available.
Clearly labelled external connection requirements are mounted on manifolds with the option of either crowsfoot or MacDonald air connections available to accept the supplementary air needed during operation. The vacuum pump and power unit assemblies are fully protected by a range of automatic shutdown devices.
Vacuum Filtration Unit
The filter unit is housed within a specifically designed skid frame that can allow operation at a self-supported elevated level to ensure problem free suction at all times. The vacuum filter unit contains a bank of high temperature and chemical resistant dust filters, which are self cleaned using a pneumatic pulsation system.
HEPA Filtration Unit
The filter unit is of stainless steel construction contained within a certified lifting frame and is fitted with Interchangeable type EU13 (99.99-99.999%) High Efficiency Particulate Arrestance (HEPA) filters. Easily removed inspection panels on the HEPA filtration unit provides ready access to the filter magazine thus ensuring that condition monitoring and cartridge replacement are straightforward operations.
Vacuum Discharge Hopper
Pneumatically controlled and ATEX certified, during operation allows material to be transferred from the hopper to a waiting container (vacuum skip) by an air driven conveyor. Strategically placed air hammers and vibrators prevent bridging of material within the unit. During transit the auger boom folds in two and is securely stored underneath the hopper. The hopper has been designed to allow continuous media removal to take place even during changeover between vacuum skips.
Designed to be stackable to optimise space, the skips have an inlet and outlet port with camlock connectors and a hinged, sealed lid.
