Stainless Steel Pumps
Haight Pump offers stainless steel pumps, adding to the Haight product family of pumps. The company has combined the versatile Universal Series pump design with stainless steel and corrosion resistant materials to meet the needs of ever changing process systems, delivering rugged, reliable, and innovative pumps. There are only two moving parts; a stainless steel outer gear and a plastic inner gear engineered to match the exact application. Hydraulic balancing ensures reliability and minimises wear. Its distinctive operating characteristics make the pump ideal for use with corrosive, high temperature, thin, corrosive and other aggressive problem fluids. Typical fluids include: phosphoric acid, caustic sodas, zylene, polymers, surfactants, flocculants, carbon black, isocyanates, sodium hydroxide, glycols, wastewater and other chemicals. Before the advent of this series, end users had to deal with galling, pump failures and unscheduled down- time. The stainless steel pumps in the Universal Series solve these problems with features not found in other gear pumps of this kind. These include: no galling – ensured by pump design and high hardness materials of construction; shaft alignment – close coupling eliminates alignment and run out; no gearboxes – operate at standard motor speeds without the need for a gear reducer; 316 L stainless, low carbon steel – shaft, housing, pinion gear for better corrosion resistance and low lubricity; reduced pump inventory needs – one pump handles multiple service requirements; and maintenance – easy service and inspection accessibility. With the advent of the universal design, all pumps in the standard Haight product line are able to accept relief valves, lip seals, four types of mechanical seals or packing gland shaft seals. It is the only design on the market that allows end users to switch sealing methods on-line and in-place without the need for special tools. Operating characteristics include: capacities of 6, 7, 8, 9, 10, 15 and 20 gpm; lubricating fluids to 250 psid; non-lubricating fluids to 100 psid; temperature range from -40°F to 250°F; standard motor operating speeds of 900/1200/1800 rpm; inlet capacity of 20"Hg lift to 250 psi; and viscosity range from 32 SSU to 10,000 SSU.
