WPWV Universal Worm Gear Reducer \u2014 Vertical Flange Mount for Pump Drives, Top-Entry Agitators & Vertical Process Equipment<\/h1>\n

When a pump drive, vessel agitator, or vertical conveyor head needs to be fed from a worm gearbox mounted directly above \u2014 with the output shaft pointing vertically downward to connect directly to the pump shaft or agitator stub \u2014 the WPWV universal vertical flange-mount worm gear reducer<\/strong> is the purpose-designed solution. The WPWV housing is configured for vertical output with correct oil lubrication in the upright position and a flange mounting face for bolt-down attachment to pump heads, vessel top flanges, and vertical machine mounting structures.<\/p>\n

The compact vertical configuration (no separate right-angle drive required) and self-locking at high ratios make the WPWV the efficient, safe, and low-maintenance choice for agricultural pump stations, food vessel drives, and vertical process equipment across a wide range of industries. Available in 12 sizes<\/strong> (40\u2013250 mm), ratios 1\/5\u20131\/60, three shaft-direction positions. About Ever-power<\/a> | Get a Vertical Drive Quote<\/a><\/p>\n<\/section>\n

\u2705 Key Features & Benefits<\/h2>\n
\n
\n
\u2b06\ufe0f<\/div>\n

Vertical Output \u2014 No Right-Angle Adapter Required<\/h3>\n

The WPWV delivers its output shaft vertically from a horizontal worm gear set in a single compact housing \u2014 no separate right-angle bevel gear adapter, no additional coupling, no extra alignment interface. This saves height, weight, and mechanical complexity in pump station and vessel agitator top-entry drives. Keywords: vertical output universal worm reducer, pump drive worm gearbox flange mount.<\/em><\/p>\n<\/div>\n

\n
<\/div>\n

Correct Oil Lubrication in Vertical Position<\/h3>\n

The WPWV oil system is configured for vertical operation \u2014 ensuring correct gear mesh and bearing immersion when the unit is in its normal upright operating position. A horizontal gearbox used vertically without proper reconfiguration runs with inadequate lubrication at the high gear end, leading to accelerated wear.<\/p>\n<\/div>\n

\n
<\/div>\n

Self-Locking Prevents Pump and Agitator Back-Drive<\/h3>\n

At ratios of 1\/30 and above, the WPWV self-locks under static conditions \u2014 preventing pump back-spinning, agitator gravity reversal, and vertical conveyor carrier slide-back when the motor is de-energised. This eliminates the need for a check valve or shaft brake in many pump and agitator applications.<\/p>\n<\/div>\n

\n
\ufe0f<\/div>\n

Flange Mounting Face for Direct Pump\/Vessel Connection<\/h3>\n

The WPWV flat flange mounting face bolts directly to standard pump head flanges, vessel top nozzle plates, and vertical machine mounting structures \u2014 without adapter plates. This makes installation straightforward and provides a rigid, leak-free mechanical interface between the gearbox and the driven equipment structure.<\/p>\n<\/div>\n

\n
\u2699\ufe0f<\/div>\n

Smooth Quiet Drive for Agitator Applications<\/h3>\n

The precision gear pair (\u226472 dB(A)) delivers smooth, vibration-free output essential for vessel agitator applications where gear-induced vibration could affect mixing quality, fluid stability, or the integrity of fragile process materials.<\/p>\n<\/div>\n

\n
<\/div>\n

12 Sizes for All Vertical Drive Requirements<\/h3>\n

Twelve sizes from 40 to 250 mm cover vertical pump drives from small agricultural irrigation pumps (size 40) to large industrial pump station drives (size 250) \u2014 all from a single standardised vertical flange-mount product.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

ISO 9001:2015 & CE<\/h3>\n

Full ISO 9001:2015 QMS. CE Declaration of Conformity per shipment. Vertical position oil fill verified before shipment. Flange mounting face flatness verified (\u22640.05 mm TIR) to ensure correct pump or vessel contact without shimming.<\/p>\n<\/div>\n

\n

\u2b06\ufe0f Vertical Orientation Run Test<\/h3>\n

Each WPWV is run-tested in its vertical operating position \u2014 not horizontal. Oil temperature, noise (\u226472 dB(A)), and seal integrity are all verified in the upright orientation before shipment is approved. This ensures the product has been validated in its actual service condition.<\/p>\n<\/div>\n
