Vacuum Dewatering Pump – 5HP, Concrete Flooring, 35sqm

The 5 HP Vacuum Dewatering Pump is the standard-capacity machine for the Vacuum Dewatered Flooring (VDF / Trimix) process — it draws excess water out of a freshly laid concrete floor slab through vacuum mats, so the floor gains strength faster and finishes harder. Its 5 HP motor dewaters roughly 35 sqm in one operation, ideal for small to medium floor areas. Electric-motor driven, mounted on a transport trolley.

What vacuum dewatering does for a floor

Concrete is mixed with more water than it needs to cure, because the extra water makes it workable enough to place and level. That surplus water is also what weakens the finished slab. The vacuum dewatering process removes it: right after the slab is laid and screeded, vacuum mats are placed over the surface and this pump pulls the excess water out through them before the concrete sets.

Taking that water out lowers the water-cement ratio in the slab, which is what gives a vacuum-dewatered floor its advantages — higher compressive strength, faster early strength (close to 28-day strength reached in about 7 days), a harder, more abrasion-resistant surface, reduced shrinkage and permeability, and cement saving of roughly 15%. The floor can be walked on and finished sooner, so construction moves faster. This pump is a core part of the VDF / Trimix flooring machine set.

Which pump to choose

The pump comes in two motor sizes, and the difference is throughput — how much floor area you can dewater per operation before the concrete stiffens.

• This 5 HP pump — ~35 sqm per operation; the standard choice for small to medium floors and steady throughput.
• 7.5 HP pump — higher power and speed, ~50 sqm per operation; for large industrial floors and faster-paced pours.

Applications

Vacuum-dewatered concrete flooring for industrial floors, warehouses and container yards, runways, railway and metro platforms, canals and pathways, ports and jetty heads, bridges, heavy-vehicle depots and precast concrete products.
