WPWDKV Flange-Mounted Universal Hollow Shaft Worm Gear Reducer \u2014 IEC Motor-Direct + Coupling-Free Vertical Pump & Agitator Drive in One Unit<\/h1>\n

The most demanding specification for a vertical pump or agitator drive is zero couplings at both ends: IEC motor direct-mount at the top (no input coupling), and coupling-free hollow shaft engagement at the bottom (no output coupling at the pump or agitator shaft), in a correctly lubricated vertical configuration that bolts directly to the pump head or vessel nozzle flange. The WPWDKV flange-mounted universal hollow shaft vertical worm gear reducer<\/strong> delivers exactly this specification in one product.<\/p>\n

The WPWDKV is the premium motor-direct specification for pump stations, vessel agitator top-entry drives, and vertical process equipment \u2014 combining IEC motor convenience with coupling-free hollow shaft pump engagement and self-locking pump anti-back-spin. Motors 0.12\u201315 kW, bore 16\u2013110 mm, ratios 1\/5\u20131\/60. About Ever-power<\/a> | Request a Pump Drive Consultation<\/a><\/p>\n<\/section>\n

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

Zero Couplings at Both Ends in Vertical Pump Configuration<\/h3>\n

The WPWDKV is the only WPW product providing IEC motor-direct input AND hollow bore coupling-free pump shaft output in a correctly configured vertical housing. WPWDKT has both zero-coupling features but is configured for inclined service; WPWKV has hollow bore vertical but standard input shaft. WPWDKV delivers all three simultaneously for vertical pump and agitator drives. Keywords: IEC flange hollow shaft vertical pump drive worm reducer, motor-direct coupling-free agitator worm gearbox.<\/em><\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

IEC Motor Swap at the Pump Head \u2014 No Pump Disturbance<\/h3>\n

When the motor fails on a WPWDKV-driven pump, the IEC flange allows motor replacement without removing or disturbing the pump shaft connection. For pump station drives where pump removal means system shutdown, this motor-swap-only maintenance procedure has direct commercial value.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

Self-Locking Prevents Pump Back-Spin at Motor Stop<\/h3>\n

At ratios \u22651\/30, the WPWDKV self-locks \u2014 preventing pump impeller back-spin driven by system pressure after motor stop. The hollow bore ensures the pump shaft is rigidly engaged while self-locking holds. For pump stations where water hammer from reverse rotation is a risk, WPWDKV self-locking provides passive protection without a check valve.<\/p>\n<\/div>\n<\/div>\n

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

Three-in-One Mounting Simplicity<\/h3>\n

The WPWDKV mounting procedure involves: bolt IEC flange to motor (top), bolt mounting face to pump head (bottom), insert pump shaft into hollow bore (bottom). Three clean interfaces, zero couplings, zero alignment tasks \u2014 the simplest zero-coupling vertical pump drive assembly procedure available.<\/p>\n<\/div>\n<\/div>\n

\n
<\/div>\n
\n

Hygiene and Compactness for Food & Beverage Vessels<\/h3>\n

The IEC flange and hollow bore eliminate all coupling hardware from both the motor connection and the agitator shaft connection above and below the gearbox \u2014 removing contamination risk points and reducing the total drive assembly height above the vessel, important in space-constrained food and beverage production facilities.<\/p>\n<\/div>\n<\/div>\n
