PUMPS & DRAINAGE
Pumps
Griswold Controls pioneered automatic flow control with the introduction of its stainless steel flow cartridge in 1960. From the original 100% stainless steel cartridge for automatic flow controls, to the Automizer® the first combination actuated control ball valve with automatic flow limit controls, Griswold Controls is the leader in HVAC technology for flow control.
Drainage
Over thirty years ago, NDS, Inc. manufactured the first plastic catch basin, and a tradition of innovation, quality products, and water management solutions began. Today, NDS is the industry's primary source for solutions in stormwater management, efficient landscape irrigation, and water management valves for the residential and non-residential markets.
Over 40 yeas ago, ADS recognized the ineffective materials being used for drainage and surface water control and developed a structurally superior corrugated polyethylene pipe that was perfectly suited for subsurface drainage. Lightweight construction, high resistance to corrosion and abrasion, and strength and durability to withstand severe loading conditions has made the ADS pipe the clear choice for applications in agriculture, mining, forestry, recreation, and civil engineered construction projects.
