WPWEKO Double Speed Cast Iron Worm Reducer — WP Series

The WPWEKO combines WPW universal body, K-type hollow bore output in vertical upward direction, and dual worm stages — ratios 1/200–1/900+, output torque up to 6,050 Nm. Universal shaft directions, coupling-free vertical agitator shaft insertion at extreme ratios.

Deskripsi

WPWEKO Double Speed Cast Iron Worm Reducer — Product Overview

Vertical agitator and mixer shaft applications that require coupling-free shaft insertion and extreme ratio reduction use the WPWEKO universal hollow bore vertical drive. The K-type hollow bore eliminates the output coupling at the agitator shaft interface; the O-type vertical orientation connects directly upward; the WPW universal body accommodates multiple motor position configurations; and the dual worm stages provide ratios from 1/200 to 1/900+.

WPWEKO Double Speed Worm Reducer — Core Features

■ K Hollow Bore + O Vertical + Universal WPW Body + Double Stage

The WPWEKO provides coupling-free vertical upward shaft insertion (K+O) with universal WPW shaft direction input flexibility and dual-stage extreme ratios — the universal platform for hollow bore vertical agitator shaft drives at 1/200–1/900+.

■ K Hollow Bore + O Vertical — Coupling-Free Vertical Shaft Connection

Agitator shaft inserts directly through the K-type vertical hollow bore. No coupling at the vessel shaft interface in any WPW input shaft direction configuration.

■ Universal WPW Body — Multiple Input Directions for Vertical Hollow Bore Drive

WPW universal body flexibility extends to the K+O configuration — multiple motor position requirements covered by a single WPWEKO product model.

■ Same 6,050 Nm Torque as WPEO — Hollow Bore Vertical Does Not Reduce Capacity

WPWEKO worm gear internals are identical to WPEO at equivalent size combinations. K+O+universal body designation does not reduce torque ratings.

■ Dual Independent Oil Chambers — O-Type Adjusted Volumes

Two independently sealed chambers with O-type vertical adjusted oil volumes. Oil volumes specified per WPW shaft direction in the WPWEKO lubrication table.

■ FC20+ Universal Dual-Chamber Housing — Vertical K+O Geometry Stable

Cast iron dual-chamber housing maintains K-bore alignment and inter-stage geometry in O-type vertical orientation across all WPW shaft direction configurations.

WPWEKO Worm Reducer — Industry Applications

WPWEKO double speed worm reducer applications

⚔ Universal Hollow Bore Vertical Agitator Platform

WPWEKO provides coupling-free agitator shaft connection with vertical upward output and universal motor position flexibility — the complete specification for hollow bore vertical agitator drives in process plant environments.

☵ Multi-Direction Motor Position Vessel Shaft Drives

Chemical and food process vessels with agitator shaft drives requiring K-bore vertical connection and varying motor positions use WPWEKO universal body to cover all installation configurations with one product.

⚒ Extreme-Ratio Hollow Bore Lift Mechanisms

WPWEKO Double Speed Worm Reducer — Customer Reviews

★★★★★

“WPWEKO on our vessel agitator shaft drives. K-bore accepts the agitator shaft directly — no coupling at the vessel. Universal WPW body covers motor positions in two different vessel configurations with one product model.”

Perth — A.S.
★★★★★

“Used WPWEKO on our food processing vertical mixer drives. Hollow bore eliminates the coupling in the product zone. Universal body accommodates our two different motor position constraints. One product, all our vertical mixer positions.”

Melbourne — L.K.
★★★★★

“WPWEKO on slow vertical lift mechanisms. K-bore shaft connection, universal input direction, extreme ratio. Coupling-free vertical shaft connection at ultra-slow output speed — exactly the specification we needed.”

Singapore — B.N.
★★★★☆

“Good K+O+universal combination. WPWEKO-70–120 on our vessel agitator drives. All features working. Would appreciate a combined K+O oil volume table to simplify our maintenance documentation.”

Frequently Asked Questions — WPWEKO Double Speed Worm Reducer

▶ What distinguishes WPWEKO from WPEKO?
The WPEKO uses a standard WPE housing with a fixed A-type input shaft direction. The WPWEKO uses the WPW universal body accommodating multiple input shaft directions. Both have K hollow bore vertical upward output and dual-stage extreme ratios.
▶ What hollow bore diameters are available in WPWEKO?
WPWEKO hollow bore diameters match the WPEKA series: 18.8 mm (size 40–70) through 90 mm (size 155–250). GB/T 1095 standard keyways.
▶ How is the agitator shaft secured in the WPWEKO K-type vertical bore?
Insert the agitator shaft vertically upward into the K hollow bore until the shoulder. Install the key in the aligned keyway. Tighten set screws to specified torque. The unit is now coupled directly to the agitator shaft.
▶ Are oil volumes adjusted for K+O vertical hollow bore orientation in WPWEKO?
Yes. O-type vertical upward orientation requires adjusted oil volumes in both stage chambers. Use the WPWEKO lubrication table for the correct volume at each WPW shaft direction.
▶ What is the maximum output torque for WPWEKO?
WPWEKO size combination 155–250 delivers up to 6,050 Nm — identical to WPEO and WPWEO since all A-type input WPE variants share the same worm gear internals.
