11 Nov Hold Back the Flow with Aluminum Stop Logs
Isolation for Emergencies and Maintenance
The 500 Series Aluminum Stop Logs from Whipps, Inc. are a modern, high-performance solution for water containment in ponds, tanks, channels, and other flow control applications. Unlike traditional timber stop logs, which can suffer from dimensional instability and unpredictable leakage, our precision-fabricated aluminum logs provide reliable, consistent sealing with long-term durability.
In continuous production since 1977, Whipps stop logs have set the standard for lightweight handling, dependable sealing, and cost-effective performance. Wastewater treatment plant operators can count on consistent water control across a wide range of depths and channel widths. Installation flexibility is built in. Whipps offers multiple mounting arrangements and custom configurations.
Breakdown of the 500 Series
Each stop log is designed to be lightweight, corrosion-resistant, and dimensionally stable, making them easier to install and remove, especially in applications where adjustments are infrequent. With a guaranteed leakage rate of only 0.05 gallons per minute per linear foot of wetted seal, the 500 series stop logs meet or exceed the AWWA standard. All models feature aluminum construction with UHMW seat/seals, ensuring both strength and resiliency under varying conditions. Combined with Whipps’ precision machining and fabrication, these stop logs deliver long-term performance while minimizing maintenance and replacement needs.
Model Differences: 509 vs. 510 vs. 511
The Whipps 500 Series includes three standard models, each engineered for specific combinations of channel width and water depth:
Model 509 – Stop Log Design
The Whipps Model 509 Aluminum Stop Log is a lightweight, 4-inch-thick aluminum log utilized in narrower channels and moderate water depths. Its open channel construction makes handling easy, especially in applications with infrequent installation or removal. Durable aluminum and precision seals ensure consistent, long-term water control performance.
Model 510 – Stop Log Design
The Whipps Model 510 Aluminum Stop Log provides greater strength than the 509 with a 6-inch-thick design, making it well-suited for wider open channels and deeper water. It balances rugged durability with manageable handling weight, offering dependable sealing and long-lasting performance.
Model 511 – Stop Log Design
The Whipps Model 511 Aluminum Stop Log is built for the most demanding applications, featuring an 9-inch-thick aluminum log design for maximum strength and stiffness. Ideal for large channels and higher water depths, the 511 delivers unmatched structural integrity, reliable sealing, and long service life.
