Myers S4S/SB4S Series Sewage Pumps Buyers Guide & Review

The Myers S4S and SB4S series of sewage pumps are suited to wet-well installation in a wide variety of municipal, industrial and building trades applications. Their solids handling ability makes them a wise choice for:
• Municipal sewage lift stations
• Industrial sewage transfer
• Dewatering of storm water or whenever unwanted water collects

The S4S Series handles 3 inch spherical solids and has a flanged 4 inch horizontal discharge. The SB4S Series handles 3 inch spherical solids and has a flanged 4 inch vertical discharge. 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 wastewater 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. The S4S and SB4S can be used with the Hydromatic pultruded I-beam rail system to accomplish this. This corrosion-resistant system permits the pump(s) to be lowered into position without entering or reaching into the wet well. An exclusive self-sealing flange eliminates the need to bolt pump to the piping. When the pump is activated, a neoprene diaphragm forms an effective seal between the discharge flange and the base elbow flange. A Hydromatic control panel will ensure proper start components and equal pump alternation. This corrosion-resistant NEMA 4X panel also includes float indicator L.E.D.’s, allowing float monitoring without removal of wet well cover.

Features

• Oil-filled motor for cooler operation, longer life, and less maintenance. The dielectric oil effectively dissipates heat and lubricates upper and lower ball bearings.
• Single phase motors are capacitor start, capacitor run with capacitors located in control panel. Contact distributor for proper Hydromatic control panel sizing.
• Standard construction is cast iron.
• 300 Series stainless steel shafts.
• Standard 15′ or 30′ power cord has three conductor PVC jacket.
• Field serviceable; pumps have 300 series stainless steel fasteners for easy tear down.
• Semi-open, two-vane sewage type impellers have pump-out vanes on back shrouds to prevent stringy materials from building up around shaft and seal.
• Manufactured with carbon and ceramic faced mechanical shaft seal for long leak-proof life.
• All units given complete hydraulic test run before shipping.
