Hydromatic introduces a competitively priced line of quality dual seal 3” and 4” discharge non-clog sewage pumps. The S3SD/S4SD and SB3SD/SB4SD Series of 1 through 7-1/2 HP pumps feature horizontal or vertical discharge options for quick and easy installations. The quality double ball bearing, dual mechanical seal pumps incorporate a stainless steel shaft and internal heat sensor protection. Coupled with strong performance capabilities up to 55’ head and flows up to 700 gpm. Hydromatic’s dual seal pumps are suited to wet-well installation in a wide variety of Municipal, Industrial and building trades applications.

The Hydromatic S3SD/S4SD and SB3SD/SB4SD sewage pumps are designed to transfer raw sewage with solids as large as 3 inches through pipes up to 4 inches in diameter. Sewage pumps are necessary to move sewage from a building to the sewer system; and in many cases, from the sewer system to a treatment plant. In the case of larger commercial installations, collection systems are designed to accumulate and transfer the waste water efficiently.

Examples of this are motels, apartment buildings, or Industrial plants that tie in with sewer mains or on site treatment facilities. For commercial or high volume applications, the usual procedure is to incorporate at least two pumps as a duplex system in conjunction with control panel, a guide system and quick disconnect discharge system. Hydromatic S3SD/S4SD pumps provide maximum value that can’t be beat!
