825 – Non-Self-Contained 820 Sluice Gate (includes Pedestals)

The Model 825 Gate from Whipps, Inc. is a lightweight, non-self-contained aluminum sluice gate designed for precise water control in demanding environments. Featuring a top seal to prevent overflow and pedestal-mounted operators (wall- or floor-mounted), the 825 offers flexibility in installation while maintaining excellent corrosion resistance, durability, and low leakage performance. Its aluminum construction provides strength at a lower weight and cost, making it a reliable, long-lasting solution for WWTP.

General Information

The Model 825 Sluice Gate from Whipps, Inc. is a lightweight yet durable solution for precise water control. Part of the aluminum 800 Series, the 825 features a top seal that prevents overflow and stops leakage on all sides of the opening. This makes the aluminum sluice gates well-suited for tunnels, pipelines, and applications where watertight control is critical.

Unlike the other 800 Series designs, the operator on the Model 825 is mounted on a pedestal separate from the frame. This non-self-contained configuration offers greater flexibility for installations with limited space or unique alignment requirements while still ensuring smooth, consistent gate operation. Constructed from corrosion-resistant aluminum with UHMW seals, the 825 combines long-term durability with reduced weight for easier handling, installation, and cost savings over heavier alternatives.

The Model 825 can also be specified with a variety of suffix designations to meet unique project needs. A “-D” configuration indicates a downward-opening design, classifying the gate as a weir gate, ideal for applications requiring water elevation control with limited headroom. A “-I” designation provides a dual-stem design, where operators are interconnected for balanced movement across the gate. The “-C” option adapts the gate for channel mounting, while a “-N” designates a non-rising stem, where the stem does not rise with the slide. These features can be combined in any configuration, giving engineers and operators maximum flexibility when designing a water control solution.

Every 825 is custom-fabricated to meet project specifications, providing reliable, low-leakage performance. Crafted from cost-efficient aluminum , the non-self-contained sluice gate is a water management solution our customers can count on. Working in the water control industry since 1977, Whipps, Inc.’s history of proven performance and quality speaks for itself.

Product Advantages

Superior Performance

Whipps, Inc. guarantees lower leakage than that listed in AW WA C-SOI- Cast Iron Sluice Gates or the latest revision, AWWA C-560 – Cast Iron Slide Gates. Whipps, Inc. will guarantee leakage of no more than 0.05 gpm/ft of seal perimeter in seating head and unseating head conditions. Including high head service.

Cost

Fabricated stainless steel gates almost always cost less than cast iron gates. As the size of the gate increases, the price difference increases. This is due to the manufacturing process (e.g. casting of parts and subsequent machining) required to produce cast iron gates.

Strength

The ultimate strength of stainless steel is in excess of twice the ultimate strength of cast iron and stainless steel has approximately twice the modulus of elasticity of cast iron.

Durability

Stainless steel resists corrosion better than cast iron. The uv stabilized UHMW seat/seals that are utilized on our stainless steel gates are field proven to maintain shape and integrity in demanding applications. Whipps, Inc. tested the UHMW seatjseals to confirm the ability to withstand continuous operation in an abrasive environment. The testing consisted of 25,000 gate open/close cycles in an abrasive media while experiencing only negligible wear. (Test results available upon request)

Reliability

Unlike traditional cast iron gates, the slide will not “freeze” to the frame after long periods of inactivity. Whipps, Inc. stainless steel gates incorporate UHMW seat/seals to prevent any metal-to-metal contact between the slide and the frame.

Delivery

The fabrication process required to turn raw materials into a stainless steel gate is quicker than the casting and machining process required to turn raw materials into a cast iron gate

Self-Adjusting Seals

The Series 900 stainless steel gates have a self-adjusting seal system that completely eliminates the need for field adjustment. This seal system was developed with the understanding that many gates are installed in locations where field adjustment of wedges is not practical or possible. Another drawback to a wedged system is that wedge adjustment is an inexact science. Wedge adjustment when attempted by inexperienced personnel can lead to additional leakage, difficult gate operation and increased localized gate stresses. The self-adjusting seal system is a combination of durable UHMW seatjseals and a resilient static spring/seal. The UHMW seat/seals are shaped to form a low friction, yet tight, seal with the slide. The spring/seal serves two main purposes: First; it acts as a bulb seal etween the frame and the UHMW seat/seal and secondly; it acts as a “spring” to ensure continuous contact between the UHMW seat; seals and the slide. The spring/seal is stationary, similar to an O-ring seal. and it is protected from wear or damage from the movable slide by the UHMW seatjseals. (Wedges can be provided on our Series 900, but they are not recommended since they do not improve the performance of our gate.)

Low Maintenance

Stainless steel gates do not require periodic painting, and require less operator attention compared to cast iron gates.

Ease of Repair

In the unusual event that the seat/seals are damaged, they can be replaced in the field with common tools. The gate does not have to be removed from the wall. If the seating surface on a cast iron gate is damaged, the gate will have to be removed from the wall and shipped back to the manufacturer for re-manufacture.

Range of Sizes

The process to design and manufacture fabricated gates allows for a nearly unlimited range of sizes. This is not the case with cast iron gates since new patterns or modifications to existing patterns are required to accommodate unusual sizes.

Mounting Configurations

Gate frames may be embedded in the channel walls. mounted to a wall with anchor bolts, mounted to a pipe flange, or wall thimble. Wall thimble mounting is possible although it is usually only necessary for applications with high unseating heads. Gates can also be designed to mount to existing wall thimbles or existing pipe flanges. Flanged frames or flat frames are available for gates to cover square, rectangular or round openings in concrete structures.
