SV Solids Pumps, slurry pumps and sludge pumps have the capability of recovering material by two modes, the first being ‘pure vacuum’ whilst the second is ‘air conveying’.
As a general rule, pure vacuum would be used for removing sludge from beneath liquid or for rapid liquid loading or slurry loading within close proximity to the machine. In this mode, the vacuum tube is totally submersed in the liquid and only material (no air) transports through the line.
The maximum vertical suction lift from the machine to the surface cannot exceed 9.2 metres at sea level assuming water is the liquid. Horizontal suction distances would be greater.
For materials of a higher density than water, these figures must be reduced accordingly. This mode is a conventional pumping technique with the material being displaced by negative pressure.
However, the SV solids pumps, slurry pumps and sludge pumps can transcend conventional pumping techniques by pneumatically conveying materials.
Pneumatic conveying is a method of handling materials by utilising high velocity airflow with a pipeline. This requires sufficient air velocity to pass the material being picked up to capture it and convey it through the vacuum tube to the machine.
The advantages of this technique are:
• Suction lifts up to 25m (82ft)+ vertically can be achieved
• Materials can be liquid or dry
• Particle sizes of up to 70% of pipe diameter can be conveyed
• Horizontal suction distances in excess of 60m (200ft) can be achieved
• Fibrous, waxy and heavy sludge can be handled
• Powders and solids can be handled as well as wet materials
There are also applications where a vacuum fluidising tube should be used which combines the benefits of pure vacuum and pneumatic conveyance when removal of material from beneath liquids is required where the distance exceeds the limitation of pure vacuum.
The SV Solids Pumps are designed to convey recovered material under pressure through a pipeline or into a collection vessel. Alternatively, deadheads and cuttings carousels are available which absorb and dissipate the discharge pressure and allow the delivery of material under gravity to a confined location such as a conveyor belt or drill cuttings skip.
Two modes of positive pressure discharge are used in SV Solids Pumps; dense phase and lean phase pneumatic conveying. The latter can achieve vertical heads in excess of 35m (115ft) and horizontal discharge distances of over 1000m (3280ft).
The absence of any electrical supply in SV Solids Pumps makes them useful in restricted or potentially hazardous areas.
