Applications

Features • All Bronze Pump Castings • Stainless Steel Motor Shaft • Mechanical Seal • Extremely Quiet • Will handle difficult solvents with proper seals Viton S10 or Teflon S11 • Long Life • Do Not Require Relief Valves • Will Handle Contaminated Liquids Applications The special pump alloys used provide corrosion resistance to many liquids including water, water solutions, and a wide range of commercial chemicals. Questions as to the chemical compatibility of special liquids should be referred to the factory. Viscous liquids with a maximum viscosity of 2000 Saybolt Seconds Universal can be pumped. However, when pumping viscous liquids as compared with water, a reduction inflow and pressure occurs and the required horsepower rate increases. Liquids heavier than water require additional horsepower in direct proportion to the increase in specific gravity. Liquids contaminated with small solids or abrasives can be handled, but a reduction in mechanical seal life must be expected.
