کاهنده سرعت حلزونی چدنی دو سرعته WPEDO — سری WP

The WPEDO addresses the intersection of three common vertical agitator drive requirements simultaneously: direct IEC motor mounting without an adaptor plate, vertical upward output shaft direction, and extreme ratio reduction to output speeds below 5 rpm. All three are delivered in a single foot-mount dual-chamber FC20+ cast iron housing — eliminating the motor adaptor, the right-angle output bracket, and the VFD speed controller that alternative approaches require.

■ IEC Motor Flange + O Vertical Output + Double Stage — Three Functions

Combines direct IEC motor mounting (no adaptor), O-type vertical upward output shaft, and two-stage extreme ratio reduction in one FC20+ cast iron housing — the complete solution for motorised ultra-slow vertical agitator drives.

■ D-Type Split Housing — In-Situ Inspection on Agitator Frame

The D-split cover removes while the motor and vertical output shaft remain connected. Both worm stage chambers are accessible for worm wheel inspection during planned maintenance intervals without removing the unit from the agitator mounting frame.

■ Output Torque to 9,066 Nm — Full WPEDO Capacity

IEC flange and O-type output do not reduce the dual-stage worm gear torque capacity. WPEDO size 155–250 delivers up to 9,066 Nm — identical to WPEDA.

■ Independent Dual Oil Chambers — O-Type Adjusted Volumes

Both stage chambers are independently sealed with separate oil fills adjusted for O-type vertical output orientation. Use the WPEDO lubrication table for correct volumes.

■ IEC 72-1 Flange — Motor Bolts on in Four Bolts

Standard IEC motor flanges (A02/Y-series, frames 56–300 depending on size) connect directly without adaptor plate or coupling — same motor hardware as the WPDA.

■ FC20+ Dual-Chamber Housing — Agitator Environment Rating

Cast iron housing resists process fluid splash and moisture in agitator installations. Both gear chambers independently sealed against cross-contamination.

⚔ Wastewater & Sludge Agitator Drives

WPEDO direct IEC motor flange eliminates the motor adaptor from agitator drive BOM. O-type vertical output connects to agitator shaft. D-split cover enables in-situ inspection during planned maintenance windows on the agitator frame.

☵ Chemical Reactor Slow Agitators

Extreme ratio direct-motor drive for slow-speed chemical reactor agitators requiring speeds below 3 rpm. No VFD required. D-split cover for annual gear inspection without vessel shutdown.

⚒ Food & Beverage Batch Mixer Drives

IEC motor direct, vertical upward output for bottom-entry vessel mixers, D-split hygiene inspection access. WPEDO covers the complete requirement list for food plant vertical batch mixer drives.

⚊ Slow Lift & Hoisting Mechanisms

Ultra-low speed vertical lift mechanisms requiring direct IEC motor input and output torques to 9,066 Nm use WPEDO without intermediate coupling or adaptor hardware.

■ ISO 9001:2000 — Dual-Stage Assembly Certified

Both worm stage assemblies are manufactured and tested under ISO 9001:2000. Inter-stage alignment and ratio accuracy are verified before final assembly of every unit.

■ نشان CE — دستورالعمل ماشین‌آلات اتحادیه اروپا 2006/42/EC

Full CE compliance for export to EU, UK, Australian, and New Zealand markets without re-certification.

■ آزمایش‌های قبل از حمل و نقل: نویز، نشتی، گشتاور

Noise below 68 dB(A) at rated load, 30-minute pressurisation of both gear chambers, and output torque within ±5% of rated. Non-conforming units reworked before shipment.

■ گواهینامه مواد FC20+

Both housings carry FC20 mill certificates: 220 MPa minimum tensile strength, 160–200 HB hardness. Ultrasonic testing on size combinations 135–200 and above.

“WPEDO on our sludge treatment agitators. IEC motor direct, vertical output shaft, D-split for annual inspection — no adaptor, no right-angle bracket, no VFD. Everything we needed in one unit.”

“Used WPEDO-100–155 on our chemical reactor agitators. Direct motor at 1/800 ratio, 2,100 Nm output, vertical shaft, split cover inspection in-situ on the vessel frame. Excellent design.”

“WPEDO on our food plant batch mixer drives. IEC motor direct, vertical upward output for bottom-entry, D-split hygiene inspection. Reduced our drive BOM by three components per vessel.”

“Good IEC+O+D-split combination. WPEDO-80–135 on slow chemical process agitators. All features as described. Would appreciate a published O-type oil volume table in the product documentation.”
