Wanna DU1300 vacuum belt filters

Wanna’s DU rubber-belt vacuum-filter listing groups these six configurations under effective width 1,300 mm. The original table shares body width 1,800 mm and height 2,060 mm across this group. [1] The table below preserves the individual areas, lengths, masses and vacuum-demand values. Select a defined row when requesting an updated proposal.

*The supplier prints “vacuum consumption (0.053 MPa), m³/min”. Whether this is gauge/absolute pressure and the gas-volume reference conditions are not resolved in the reviewed text. Confirm the basis before specifying a pump.

For the 9.1 m² row, the published effective dimensions give 1.3 m × 7.0 m = 9.1 m². That checks the geometry only. It supplies no dry-solids tonnes per hour, cake moisture, filtrate quality or washing endpoint. No reviewed Wanna test curve gives those results for a defined slurry.

A useful comparison in the original range is its three 20.0 m² options: the 1,300 mm family has overall length 20,000 mm, the 1,800 mm family 15,100 mm and the 2,000 mm family 14,200 mm. Their listed masses are 11.0, 11.6 and 12.0 t respectively. [1] Thus equal area does not imply the same building arrangement. It also does not prove equal output: the actual washing/drying layout and feed performance need evaluation.

The 20.0 m² DU1300 row lists 30 m³/min at the printed 0.053 MPa condition. Do not convert that directly into slurry capacity, a kW rating or a utility cost. The reviewed page supplies neither a pump curve nor a complete process-air specification.

1. Resolve the pressure reference. Ask whether the quoted pressure is absolute or gauge and where it is measured.
2. Resolve the flow reference. Ask for suction/reference conditions, temperature and the anticipated process gas/liquid carryover.
3. Define included equipment. Identify pump, separator, condenser where applicable, seal/cooling water and instruments in the proposed package.

Request a duty-specific utility schedule with the supplier’s selected equipment and design margin explained. Do not treat the range table as a complete vacuum-system design. Any site system selection remains the responsibility of the project’s qualified engineering team.

These are labels in the original diagram, not proof that seven separate items are supplied with every filter. [1] Micronics explains that the cloth provides filtration while the rubber belt provides drainage/support, and describes washing during the cake’s passage. [2] Ask for distinct cloth/belt identifiers and materials compatible with your chemistry and temperature. No lifetime or materials guarantee is inferred here.

FLS’s primary guidance distinguishes feeds that can use vacuum filtration from those requiring pressure filtration. [3] Test representative normal and difficult feed conditions before relying on the DU proposal. The official Wanna application list is a list of possible materials, not a trial report for your concentrate or tailings.

Set factory mechanical/control checks separately from site process acceptance. State who supplies the agreed feed, water, electricity, vacuum package and operating team. Record how deviations will be investigated and corrected before signing acceptance. This page reports no completed Wanna test or guaranteed filtration rate.
