The History of Whipps

Whipps, Inc. is a privately-owned company, founded in 1977 by George and Pauline Whipps. Since the company's inception, Whipps, Inc. has steadily increased market share by manufacturing water control gates of the highest quality and highest performance at a competitive price. Fabricated equipment such as sluice/slide gates (aka penstocks), stop logs, hand-pull stop gates, flap gates, shear gates, mud valves, telescoping valves and tilting weirs are produced at the company headquarters in Athol, Massachusetts.

Series 900 Stainless Steel Gates offer high performance and long life in designs which accommodate a wide range of mounting arrangements and flow conditions. Rugged, reinforced stainless steel construction is combined with tough, flexible ultra-high molecular weight polyethylene (UHMW) seat/seals, to provide a heavy-duty assembly.  Flush bottom closure is provided by a resilient bottom seal.  In addition to the wide range of standard gates, Whipps Inc. can quickly and economically produce standard gates or gates customized for unusual applications.

Aluminum Stop Logs have been used for many years to contain water in ponds, tanks, or channels. They are used in applications where their installation or removal is required infrequently. Historically, stop logs have been made from squared timbers as their name suggests. The availability of wood in the sizes, quality and quantity to make traditional stop logs has become increasingly difficult. The lack of dimensional stability in wood also makes it very difficult to provide timber stop logs with predictable leakage characteristics.

Whipps series 509, 510 and 511 Stop Logs are suitable for a large range of channel widths and water depths while providing a guaranteed maximum leakage rate of .05 gallons per minute per linear foot of wetted seal. This series of Aluminum Stop Logs has been in continuous production since 1980 providing an affordable and effective water flow control alternative for many types of projects.

Rugged aluminum construction is combined with tough, flexible ultra-high molecular weight polyethylene (UHMW) seat/seals. This design achieves a very low level of leakage. Top gates can also be supplied in a similar rugged stainless steel design.

  • Frames: Stop Gate frames are designed to be embedded (Model 501), mounted on the face of a wall (Model 503) and mounted in an existing channel (Model 503-C). The side guides are a rugged aluminum extrusion with an easily replaceable polymer seating/sliding liner. The sill is also an aluminum extrusion with an easily replaceable neoprene flush seating surface.

  • Slides: The slide is constructed from flat aluminum plate, sufficiently reinforced for the design head conditions. An appropriate lifting handle is attached near the top of the slide.

  • Leakage: The superior design of the polymer seating surfaces has reduced leakage for these stop gates to 0.10 gallons per minute per foot of wetted perimeter when specified.

Series 450 Flap Gates are used for backflow prevention in gravity flow; pump discharge and tidal applications. Fabricated Flap Gates offer high performance and long life in designs that accommodate a wide range of mounting arrangements and flow conditions. Rugged, reinforced construction is combined with a resilient seal to provide a heavy-duty, low leakage flap gate. Whipps, Inc. can economically produce customized flap gates for standard and nonstandard applications. Fabricated flap gates are typically constructed of corrosion resisting materials such as stainless steel, rubber or aluminum
