Separator/Purifier · Separators & Purifiers
The data sheet filed for the WHPX-410 describes the solids-ejecting centrifuge type WHPX 410TGD-24G, used for cleaning cutting and grinding oils. Recovered waste oil can serve as fuel or fuel supplement, and the sheet also names upgrading of residual fuels. Feed enters the rotating bowl from the top and passes a distributor into the disc stack. Oil leaves through a paring disc, water goes over the top disc and out through a second paring disc, and solids collect at the bowl periphery for intermittent discharge.
A hydraulic system lowers the sliding bowl bottom at preset intervals to open the solids ports, ejecting sludge in small portions while the oil flow continues, with virtually no oil lost. The bowl can be set up as a purifier or as a clarifier. A vertical spindle carries the bowl and a horizontally mounted motor turns it through a worm gear. Parts exposed to heavy wear from feed solids, such as the sliding bowl bottom and sludge ports, are erosion-protected. Maximum throughput is 16 m3/h and maximum solids-handling capacity is 126 l/h.
Feed temperature may range from 0 to 100 degrees C. Installed motor power is 11 kW, while the electric power drawn is 4.5 to 8.1 kW depending on feed flowrate. Each discharge uses 1.4 l of discharge and make-up liquid. Noise level is 84 dB(A) to ISO 3744 or 3746. Wetted bowl parts are stainless steel of a high grade, apart from the top disc, which is red metal; gaskets are nitrile, and main connections can follow SMS standard. Shipping data for the centrifuge with bowl and motor are 1151 kg net, 1251 kg gross and 2.7 m3.

What our service work and the manufacturer documentation say about keeping this model running.
Confirm the exact separator specification and intended duty before dismantling or changing bowl components. Inspect the bowl, disc stack, spindle, bearings, drive train, seals and all process passages for deposits, corrosion, erosion and wear. Where automatic operating-water or sludge-discharge functions are fitted, test their sequence and valve condition after service. Monitor vibration, noise and cleaned-oil quality after reassembly. All exact service intervals, tolerances, tightening values and process settings must be taken from the relevant manufacturer documentation.
Carry the manufacturer-recommended service kit for the exact serial number and separator specification. Depending on the design, additional critical spares may include bearings, seals, drive components, bowl-service parts and operating-water or control-valve components. Do not rely on apparent similarity between separator families when selecting parts.
