WPWDA Flange-Mounted Universal Worm Gear Reducer — Motor-Direct IEC Input with Multi-Direction Output for Vessels, Agitators & Agricultural Equipment
When a chemical reactor, agricultural elevator, or vessel agitator needs both the installation simplicity of motor-direct IEC flange input AND the output shaft direction flexibility to connect directly to a driven shaft at a non-standard angle — without right-angle adapter boxes — the WPWDA flange-mounted universal worm gear reducer delivers both simultaneously. Combining the IEC motor direct input of the WPWD with the extended multi-direction output geometry of the WPWA in one casting, the WPWDA is the most flexible motor-direct drive in the WPW universal series.
Motor powers from 0.12 kW to 15 kW, 12 size groups (40–250 mm), ratios 1/5–1/60. Extended output shaft (LL, M, N, E, F, G dimensions) accommodates vessel agitator head connections and agricultural shaft drives at varied angles. About Ever-power | Request a Motor Compatibility Check

✅ Key Features & Benefits
IEC Motor Direct + Multi-Direction Output — Two Features Together
The WPWDA uniquely combines IEC motor direct-mount (no input coupling) with extended multi-direction output shaft geometry. No other single product in the WPW series provides both: WPWD has motor-direct but standard output; WPWA has multi-direction output but standard input shaft. WPWDA delivers both simultaneously. Keywords: motor-direct multi-direction universal worm reducer, IEC flange extended output worm gearbox.
Extended Output Shaft for Long-Reach Agitator Connections
The extended LL housing body and E, F, G output geometry provide the clearance needed to connect to vessel agitator shafts, tall-mounted agricultural auger heads, and elevated machine drive shafts where the gearbox must sit above or beside the driven shaft connection point.
Universal Flanged Base — Mount at Any Angle
The WPW universal flanged base allows the WPWDA to be mounted in any of the supported orientations with correct oil lubrication in each position. Multi-face oil ports confirm correct gear immersion whether the unit is horizontal, inclined, or vertical.
Rapid Motor Swap in Multi-Orientation Installations
The IEC pilot register allows motor replacement in under 15 minutes regardless of mounting orientation — a particular advantage for food processing and pharmaceutical multi-angle machine drives where motor downtime must be minimised without disassembling the machine structure.
Wide Motor Range — 0.12 to 15 kW
Twelve size groups accepting 0.12 kW to 15 kW motors provide the complete range of chemical vessel, agricultural equipment, and general industry motor-direct multi-direction drive requirements from small laboratory agitators to large industrial vessel drives.
Self-Locking for Safe Load Holding in Any Position
At ratios ≥1/30, the WPWDA self-locks in any supported mounting orientation — providing passive load holding for agitators, augers, and elevated equipment when the motor is de-energised, regardless of the output shaft direction.
Industry Applications
The WPWDA is specified where motor-direct input convenience must be combined with extended multi-direction output flexibility:
Chemical Vessel AgitatorsTop-entry and side-entry chemical vessel agitator drives where the WPWDA provides IEC direct motor mounting AND the extended output shaft direction needed to connect to the agitator shaft at the required angle without adapter boxes.
Agricultural MachineryAgricultural auger elevator drives, seed conveyor head drives, and grain handling equipment with varied motor-to-shaft angles where IEC motor-direct convenience is required alongside output direction flexibility.
Brewery & Food VesselsFermentation vessel agitator drives, food mixing vessel drives, and brewery conditioning tank drives requiring motor-direct convenience and flexible output positioning above the vessel structure.
Inclined Machine DrivesInclined conveyor drives, tiered production line equipment drives, and non-horizontal machine structures where the WPWDA’s motor-direct input simplifies motor maintenance while the multi-direction output accommodates the inclined geometry.
Pharmaceutical EquipmentGMP-compliant pharmaceutical vessel agitator and blending equipment drives requiring IEC motor-direct operation (for clean, coupling-free motor maintenance) and output shaft direction flexibility.
General OEM MachineryMachine builders who need a single motor-direct product specification covering both standard and non-standard output shaft directions across a range of machine variants — eliminating the need for separate WPWD and WPWA product specifications.

❓ Frequently Asked Questions
What is the difference between WPWDA and WPWD?
The WPWD has an IEC motor flange and standard (non-extended) output shaft — identical to the WPW platform. The WPWDA has the same IEC motor flange but with an extended output shaft and housing body (LL, M, N, E, F, G dimensions) that supports multi-direction output shaft positions — the same extended geometry as the WPWA. Choose WPWD for standard output shaft applications; choose WPWDA when the output shaft must reach the driven equipment at a non-standard angle or longer distance.
Can I specify a custom output shaft length for the WPWDA?
Yes — the standard LL dimension is specified in the table for each size. For applications requiring a longer output shaft extension (e.g. deep-vessel agitators), custom LL extensions are available for OEM orders. Contact us with your required output shaft projection length and we will confirm availability and any tooling requirements.
Is the WPWDA available with food-grade lubricant?
Yes — on request, we factory-fill WPWDA units with NSF H1 registered food-grade gear oil. Specify at order placement. This is widely used for WPWDA units in food mixing vessel, brewery agitator, and pharmaceutical vessel agitator applications where food-safe machinery documentation is required.
What output shaft directions does the WPWDA support?
The WPWDA supports the same shaft-direction positions as the WPWA — providing multiple positions including horizontal, vertical, and intermediate angles. Contact us with your specific required output shaft direction and we will confirm the correct position and oil fill configuration for your installation layout.
What is the maximum output torque of the WPWDA?
At 1500 r/min input, size 250 with a 15 kW motor at ratio 1/60 delivers approximately 3,025 Nm (from the WPD.WPDK.WPWD.WPWDK power and torque table). Contact our engineers with your required motor power and ratio for a precise calculation.
