WPO Single Speed Cast Iron Worm Reducer — WP Series

When an application requires the driven shaft to run vertically upward — agitators, vertical lift conveyors, or bottom-entry mixer drives — standard horizontal-output worm reducers require a right-angle attachment bracket that adds cost, height, and misalignment risk. The WPO eliminates this entirely by routing the output shaft vertically upward as standard, with the motor input entering horizontally from either side via the bilateral input shaft.

Internally the WPO uses the same FC20+ cast iron housing, ZCuSn10Pb1 tin-bronze worm wheel, and 20CrMnTi worm shaft as the WPA — delivering the same 2,371 Nm maximum output torque and 95°C continuous operating capability in 12 standard frame sizes from 40–250 mm centre distance.

■ O-Type Vertical Upward Output — No Right-Angle Bracket

The output shaft exits the housing vertically upward as standard. Connects directly to agitator shafts, vertical elevators, and lift mechanisms without the right-angle bracket fabrication that solid horizontal-output units require.

■ Bilateral Horizontal Input — Motor from Either Side

Despite the vertical output, the WPO retains the bilateral horizontal worm shaft input. Connect the motor from either side of the machine frame without a mirrored unit.

■ Same 2,371 Nm Capacity as WPA — Identical Internals

O-type output direction does not affect torque capacity. All WPO sizes share torque ratings with their WPA equivalents — the worm gear internals are unchanged.

■ 12 Frame Sizes: 5 kg to 340 kg

From compact 40 mm units for small mechanism drives to 250 mm heavy-duty units for industrial agitator applications — 12 sizes covering the full range of vertical output drive requirements.

■ Oil Volume Calibrated for O-Type Orientation

The oil fill volume for WPO O-type mounting is specified separately to the WPA, ensuring adequate worm wheel submersion depth with the output shaft pointing upward.

■ FC20+ Cast Iron for Wet Process Environments

Vertical agitator and mixer installations often involve moisture or process fluid splash. FC20+ cast iron resists the corrosion that degrades aluminium housings in humid or wet process environments.

⚔ Wastewater Treatment Agitators

WPO vertical upward output connects directly to clarifier and aeration basin agitator shafts. Eliminates the right-angle attachment bracket and its associated alignment, cost, and maintenance overhead.

☵ Vertical Mixer Drives

Bottom-entry vessel mixer shafts require a vertical drive output. WPO foot-mount installation positions the motor horizontally alongside the vessel while the output drives the agitator shaft upward.

⚊ Vertical Lift Conveyors

For Z-conveyor and vertical lift systems where the drive shaft runs vertically, WPO eliminates the coupling and bevel gear stage that horizontal-output reducers require to change shaft direction.

⚛ Fan & Blower Shaft Drives

Vertical-axis fan impeller shafts connect directly to the WPO upward output without coupling. Removes coupling mass imbalance risk and eliminates coupling maintenance from the fan service schedule.

■ Pengeluaran Bertauliah ISO 9001:2000

Setiap unit dihasilkan di bawah pengurusan kualiti ISO 9001:2000. Pemeriksaan bahan mentah, pemeriksaan dalam proses dan ujian pemasangan akhir didokumenkan sepenuhnya dan boleh dikesan mengikut nombor siri setiap unit.

■ Penandaan CE — Arahan Jentera EU 2006/42/EC

Pematuhan penuh CE mengesahkan pematuhan kepada piawaian keselamatan dan reka bentuk Eropah untuk penghantaran kuasa mekanikal, sekali gus menyokong eksport ke pasaran EU, UK, Australia dan New Zealand.

■ Ujian Pra-Penghantaran: Bunyi, Kebocoran, Tork

Setiap unit lulus tiga ujian: hingar di bawah 68 dB(A) pada beban undian, ujian kebocoran tekanan 30 minit dan tork output dalam lingkungan ±5% daripada undian. Unit yang tidak mematuhi piawaian akan dibaik pulih — tidak dihantar.

■ Pensijilan Bahan FC20+

Tuangan perumah disahkan oleh sijil kilang untuk gred FC20: kekuatan tegangan minimum 220 MPa, kekerasan 160–200 HB. Ujian kecacatan ultrasonik pada saiz 135 dan ke atas.

“WPO-100 driving vertical agitators in our wastewater treatment plant. Vertical upward shaft connects directly to the agitator — no right-angle attachment bracket needed. 18 months, zero issues.”

“Used WPO-80 on our bottom-entry mixer drives. O-type configuration gave us exactly the shaft direction we needed without custom fabrication. Straightforward installation.”

“WPO-120 on our chemical dissolution vessel agitators. Bilateral horizontal motor input and vertical shaft output allowed the most compact drive arrangement above the vessel lid.”

“Good performance on vertical lift applications. WPO-60 drives our small batch elevator. Oil volume adjustment for O-orientation was straightforward following the Ever Power lubrication guide.”
