Center Pivot
Gearbox Irigasi
Heavy-duty drive units engineered for the harshest field conditions — high torque, sealed for dust & water, with multi-ratio options for every pivot system configuration.
Center Pivot Irrigation Gearbox
Ever Power's center pivot irrigation gearboxes are precision-engineered drive units for center pivot and linear move irrigation systems. Designed for 24/7 field operation, they deliver consistent torque output across varied terrain and climate conditions — from high-humidity rice paddies to arid desert agriculture.
Engineered for Field-Proven Reliability
Every gearbox leaves our factory tested under load conditions that mirror real-world agricultural environments — from freezing winters to tropical humidity.
IP65 Sealed Housing
Fully sealed against dust ingress and low-pressure water jets. Purpose-built for open-field irrigation where dirt, mud, and rain are constant factors.
High-Torque Output
Helical and bevel-helical gear pairs achieve up to 96% transmission efficiency, delivering maximum torque to the pivot drive wheel with minimal power loss.
Multi-Ratio Options
Choose from 15+ standard gear ratios (i = 10:1 to 200:1) to match any pivot span length and motor specification. Custom ratios available on request.
Pengoperasian dengan Kebisingan Rendah
Precision-ground gears with optimised tooth profiles reduce vibration noise to below 72 dB(A). Ideal for farms near residential areas and environmentally sensitive zones.
Hardened Alloy Gears
Case-hardened 20CrMnTi alloy steel gears, surface hardness HRC 58–62. Designed for a service life exceeding 20,000 hours under continuous operation.
Minimal Maintenance
Lifetime-lubricated bearing chambers and food-grade compatible grease options mean fewer service intervals — keeping your pivot system running through critical growing seasons.

Skenario Aplikasi
From small family farms to commercial agribusiness operations, Ever Power pivot gearboxes are trusted across six major agricultural environments worldwide.
Corn & Grain Farms
Long-span pivot systems covering 50–150 acres require high-torque gearboxes that run reliably for weeks without maintenance during peak growing season.
- Span lengths up to 800 m
- Heavy clay & loam terrain
- Recommended: EP-BH-80 / EP-BH-120
Vegetable Farms
Precision water delivery for vegetables demands consistent pivot speed. Our low-noise gearboxes maintain exact travel rates for uniform crop moisture distribution.
- Precise speed control
- Multiple daily cycles
- Recommended: EP-H-40 / EP-H-100
Cotton Fields
Cotton pivots often operate in sandy, dusty conditions. Our IP65-rated sealed housings prevent abrasive particle ingress that would otherwise shorten gearbox lifespan.
- Sandy soil environments
- High dust exposure
- Recommended: EP-BH-50 / EP-W-50
Golf Courses & Turf
Aesthetically sensitive environments require ultra-quiet, vibration-free operation. Our precision-ground helical gears deliver <72 dB(A) noise — barely audible from 10 meters.
- Noise-critical zones
- Nighttime operation
- Recommended: EP-H-40 / EP-H-100
Potato & Root Crops
Heavy harvest machinery creates ruts that challenge pivot mobility. Our reinforced drive units maintain full output torque even when wheels encounter uneven field surfaces.
- Uneven terrain tolerance
- High starting torque
- Recommended: EP-W-100 / EP-W-200
Arid & Desert Agriculture
Extreme heat, UV exposure, and sand storms push gearboxes to their limits. Our high-temp grease formulation and UV-resistant paint coating ensure performance up to 65°C ambient.
- Up to 65°C ambient operation
- Sand & UV resistance
- Recommended: EP-W-100 / EP-BH-120

Apa Kata Pelanggan Kami
Over 500 buyers in 60+ countries. Here's what field operators and procurement managers actually think after using our gearboxes.
"We replaced all 14 gearboxes on our pivot system with Ever Power units two seasons ago. Not a single failure so far — and that's through a Nebraska summer and a wet spring. The sealed housings are exactly what we needed for sandy soil conditions."
"Operating pivots in desert conditions at 55°C+ ambient is extremely demanding. Most gearboxes from other suppliers failed within a year. The EP-W-100 units have been running for 18 months with zero issues. The high-temperature grease option was the key."
"Procurement manager for a large soy and cotton operation. We ordered 40 units with custom gear ratios for our specific motor configuration. Ever Power's engineering team turned around the custom spec in 3 days and delivered within 28 days. Outstanding."
"The after-sales support is what sets Ever Power apart. When I had a mounting question during installation, their engineer responded via WhatsApp within 30 minutes with a detailed diagram. That level of service from a Chinese manufacturer genuinely surprised me."
"Solid product at a fair price point. We compared 4 suppliers and Ever Power offered the best combination of specs and lead time. The first shipment had a minor packaging issue but their team resolved it immediately with replacement parts at no charge."
"We irrigate 800 acres of wheat and rice. The noise level from the EP-H series is noticeably lower than our old gearboxes — our workers appreciate that. We've also seen a measurable reduction in electricity consumption since switching, which directly affects our operating costs."

What Role Does the Irrigation Gearbox
Play in the Center Pivot Irrigation System?
The center pivot irrigation gearbox — also referred to as the irrigation pivot gearbox — is a critical component that drives the system's ability to deliver precise and efficient water distribution across agricultural fields. Ever Power's gearboxes are engineered for optimal performance, durability, and reliability in demanding farming environments.
Transmisi Daya
The irrigation pivot gearbox transfers power from the motor to the wheels of the center pivot system, enabling smooth rotation around a fixed pivot point for uniform water distribution across the field.
Torque Amplification
The gearbox converts high-speed, low-torque motor input into low-speed, high-torque output — providing the force needed to move the pivot system effectively, even on uneven terrain.
Speed Regulation
Ever Power irrigation pivot gearboxes maintain consistent rotational speeds, ensuring the system operates at the desired pace for even irrigation and minimal crop stress throughout the growing season.
Durability & Load Handling
Designed to withstand harsh conditions like water, dust, and extreme temperatures, our center pivot irrigation gearboxes are built with robust materials to handle heavy loads and ensure prolonged operation.
Precision Movement
The irrigation pivot gearbox ensures precise alignment and movement of the pivot system, reducing wear on components and preventing uneven irrigation that could negatively impact crop yields and field uniformity.
