WPKS Single Speed Cast Iron Worm Reducer — WP Series

O WPKS solves a specific installation problem: applications where the motor must be positioned overhead (S-type top-entry) and the driven equipment has a keyed shaft requiring direct insertion without a coupling (K-type hollow bore). Neither the WPKA nor the WPS alone covers this combination — the WPKS provides both in a single FC20+ cast iron housing.

Typical applications include overhead-driven screw conveyors, grain augers, and turntable drives where vertical motor positioning conserves horizontal space while the hollow bore eliminates the coupling that would otherwise be exposed to crop debris, process fluids, or outdoor conditions.

■ S-Type + K-Type — Unique Shaft Routing

Top-entry solid input shaft and hollow bore output together create a drive configuration unavailable in any other single WP series unit. Motor overhead, driven shaft through the bore — both constraints satisfied.

■ Hollow Bore Diameters 18.8–90 mm

Identical bore dimensions to WPKA at every size — the same driven shaft that fits a WPKA also fits the WPKS. All keyway dimensions follow GB/T 1095.

■ Foot-Mount + Shaft-Mount in One Housing

The WPKS base plate and torque arm boss both exist in the same housing. Use foot-mount for traditional installation or shaft-mount with torque arm for direct shaft installation — no modification required.

■ Overhead Motor Reduces Horizontal Footprint

S-type top-entry positions the motor directly above the reducer, eliminating lateral motor projection. Combined with hollow bore output, WPKS achieves the most compact overhead drive-to-shaft installation in the WP series.

■ FC20+ Cast Iron — Outdoor Agricultural Duty

Grey cast iron resists the corrosion from fertiliser dust, grain chaff, and outdoor moisture that degrades aluminium housings. The WPKS is designed for outdoor agricultural and field conditions.

■ Oil Circuit for S-Type Orientation

The oil volume and internal channel geometry are calibrated for S-type mounting, ensuring the worm gear mesh receives adequate lubrication splash with the input shaft entering from above.

☷ Grain Auger & Screw Conveyor

Overhead motor above the auger head shaft keeps the motor clear of crop debris and moisture at the loading point. The hollow bore eliminates the coupling that would otherwise be exposed to the outdoor environment.

⚒ Turntable & Indexing Drives

Central shaft passes through the WPKS hollow bore enabling compact rotary drive tables where the vertical motor position minimises total machine height.

⚊ Overhead-Driven Conveyor Systems

In overhead conveyor systems where the drive unit must be above the conveyor belt, WPKS positions the motor directly overhead while the hollow bore eliminates the coupling below the drive unit.

⚙ Agricultural Irrigation Drives

Overhead motor keeps electrical components elevated above field-level soil, moisture, and crop debris while the hollow bore provides direct coupling to the irrigation pump shaft.

■ ISO 9001:2000 Sertifikalı

Her bir ünite ISO 9001:2000 kalite yönetim standardına uygun olarak üretilmektedir. Hammadde denetimi, süreç içi kontroller ve son testler belgelendirilmekte ve her bir ünitenin seri numarasına kadar takip edilebilmektedir.

■ CE İşareti — AB Makine Direktifi 2006/42/EC

CE uyumluluğunun tam olması, mekanik güç aktarımı için Avrupa güvenlik ve tasarım standartlarına uyumu teyit ederek AB, İngiltere, Avustralya ve Yeni Zelanda pazarlarına ihracatı desteklemektedir.

■ Sevkiyat Öncesi Testler: Gürültü, Sızıntı, Tork

Her bir ünite sevkiyat öncesinde üç testten geçer: nominal yükte 68 dB(A)'nın altında gürültü, 30 dakikalık basınç sızıntısı testi ve nominal değerin ±5% aralığında tork iletimi. Uygun olmayan üniteler yeniden işlenir, sevk edilmez.

■ FC20+ Malzeme Sertifikasyonu

Gövde dökümleri, FC20 sınıfı için fabrika sertifikalarıyla doğrulanır: minimum 220 MPa çekme dayanımı, 160–200 HB sertlik. 135 ve üzeri boyutlarda ultrasonik kusur testi yapılır.

“WPKS on our screw conveyor head drives where the motor must be above the equipment. K-bore on the conveyor shaft and overhead motor — exactly the configuration we needed. Zero coupling hardware.”

“Used WPKS-100 on our grain auger with overhead motor drive. Hollow bore eliminated the shaft coupling that kept failing due to seasonal crop debris ingress. No failures in two full harvest seasons.”

“WPKS on our turntable drive. Vertical motor plus hollow bore output — very compact installation. Motor overhead keeps the work area open below. Excellent.”

“Good K+S combination unit. Compact overhead drive with direct shaft connection. Would appreciate the option of a flared bore entrance to ease shaft insertion on size 135 and above.”
