800 Series – Aluminum Gates

Best Aluminum Gates for Flow Control
Made in the USA since 1977

General Information

Looking for a lightweight, cost-effective alternative to stainless steel sluice gates? The 800 Series Aluminum Gates from Whipps, Inc. deliver reliable water management performance in municipal, industrial, and environmental applications. Our aluminum sluice gates are manufactured with the durability and corrosion resistance you expect from Whipps products. Engineered with the same precision and quality as our stainless-steel gates, the 800 Series offers a versatile, economical solution for projects where reduced weight and lower cost are advantages without sacrificing long-term performance.

A hallmark of the 800 Series is its range of models tailored to site conditions and installation needs. The 821 model is designed for embedded mounting, offering secure performance in concrete structures. The 823 slide gate serves as a standard slide gate, built without a top seal to allow controlled overflow when water levels rise above the slide. For installations requiring added sealing, the 824 sluice gate includes a top seal, classifying it as a true sluice gate for handling slightly higher pressures. The 825 model is a non-self-contained design, relying on pedestals and operators for flexibility in wall- or floor-mounted setups. This range ensures that every installation has an aluminum gate optimized for its specific application.

Like their stainless-steel counterparts, the 800 Series features customizable frames for wall mounting, channel mounting, or embedding. Each reinforced aluminum slide is guided within the frame for smooth travel, and depending on gate width, dual-stem operation can be incorporated for balanced, consistent movement. All gates are fitted with UHMW seat/seals and resilient bottom seals, minimizing leakage while ensuring a tight, dependable closure.

Aluminum construction not only provides excellent corrosion resistance and structural integrity but also makes these gates easier to handle, install, and maintain. With slide thicknesses ranging from 1/4” to 3/8”, the 800 Series is built to withstand continuous service while reducing installation challenges compared to heavier materials. The result is a cost-effective sluice gate solution that maintains Whipps’ standard of performance and reliability.

From irrigation channels and treatment plants to flood control systems, the 800 Series Aluminum Gates represent a proven choice for precise, long-lasting water control. Backed by Whipps, Inc.’s decades of expertise, these gates combine lightweight design, durable sealing, and flexible configurations to deliver dependable operation for decades.

Product Advantages

Superior Performance

Whipps, Inc. provides a leakage guarantee that surpasses the specifications outlined in AWWA C-501 for Cast Iron Sluice Gates or the most recent revision of AWWA C-560 for Cast Iron Slide Gates. Our commitment ensures leakage rates not exceeding 0.10 gpm/ft of seal perimeter under both seating head and unseating head conditions, even in high head service scenarios.

Cost

Fabricated aluminum gates usually provide a cost advantage over cast iron gates. The manufacturing process for aluminum gates is generally less expensive than that of cast iron, stainless steel, and fiberglass gates.

Durability

Aluminum has proved to be a suitable material to use in most water and wastewater. Our aluminum gates feature UV-stabilized UHMW seat/seals, which are field proven to maintain shape and integrity in demanding applications. Whipps, Inc. conducted rigorous testing on UHMW seat/seals. Subjecting them to 25,000 gate open/close cycles in an abrasive media to validate their ability to withstand continuous operation with minimal wear. (Test results available upon request.)

Reliability

The slide of the aluminum gate will not ‘freeze’ to the frame after extended periods of inactivity. This is achieved through the inclusion of UHMW seat/seals, which effectively eliminate metal-to-metal contact between the slide and the frame.

Delivery

The process of fabricating an aluminum gate from raw materials is notably quick, particularly because Whipps, Inc. keeps most materials in stock.

Self-Adjusting Seals

The aluminum gates that Whipps, Inc. offer are equipped with a self-adjusting seal system that eliminates the need for field adjustments. A solution particularly advantageous for gates installed in locations where such adjustments are impractical or unfeasible. This advanced system cannot be replicated by the imprecise method of adjusting wedges, which can lead to increased leakage, localized stress, and difficulty during gate operation. Our self-adjusting seal system consists of UHMW, much more durable than rubber J or P seals. While rubber seals can crack, flatten, and/or adhere to the slide, our UV stabilized UHMW seat/seals will not. Furthermore, the seal system boasts a lower coefficient of friction compared to rubber, reducing the effort required to operate the gate.

Low Maintenance

Aluminum gates do not need periodic painting and require less operator attention when compared to cast iron or stainless steel gates.

Ease of Repair

In the rare event of the seat/seals experiencing damage, they can be readily replaced in the field using common tools, without the need to dismount the gate from the wall. In contrast, the damaged seating surface of a cast iron gate necessitates the removal of the gate from the wall and must be shipped back to the manufacturer for remanufacturing.

Range of Sizes

The process of designing and manufacturing fabricated gates offers the flexibility of producing a wide range of sizes, nearly without limits. In contrast, cast iron gates require the creation of new patterns or modifications to existing patterns to accommodate uncommon sizes.

Mounting Configurations

Gate frames can be either embedded in channel walls or mounted to a wall, pipe flange, or wall thimble. Wall thimbles are recommended for applications with high unseating head conditions. We offer flanged frames or flat frames for gates designed to cover square, rectangular, or round openings in concrete structures.
