Model HD pumps are specifically designed for difficult applications and those involving high viscosity liquids.
Typical applications include pumping oils, asphalts, chocolates, paints, lacquers, molasses, soaps, and other industrial viscous process fluids. HD pumps are known by their sturdy and simple construction.
Model PD:
Petrochemical duty pumps in carbon steel, designed for refinery and petrochemical applications.
| Capacity range: | Up to 750 gpm |
Speed: |
Up to 1750 rpm |
Differential pressure: |
Up to 250 psi |
Suction lift: |
Up to 15" Hg vacuum while priming |
Viscosity range: |
Up to 250,000 cSt |
Temperature: |
Up to 500°F |
Model PD pumps are designed for refinery and petrochemical applications, all pressure containing components are carbon steel.
Typical applications include pumping fuel oils, gasoline, lube oils, greases, and other hydrocarbon-based fluids.
PD pumps are available to meet most API 676 standards.
Model CD:
Chemical duty pumps in stainless steel, designed to handle corrosive liquids.
| Capacity range: | Up to 750 gpm |
Speed: |
Up to 1750 rpm |
Differential pressure: |
Up to 250 psi |
Suction lift: |
Up to 15" Hg vacuum while priming |
Viscosity range: |
Up to 250,000 cSt |
Temperature: |
Up to 500°F |
Model CD pumps are designed for handling corrosive liquids, primarily found in the chemical processing, food and pharmaceutical industries.
Typical applications include pumping of organic acids, fatty acids, alkalis, caustic soda, polymer solutions, soap, shampoo, animal fat, vegetable fat, chocolate , and other special fluids.
Model MD:
Magnetic Drive pumps are environmentally friendly pumps used for ultimate protection against leakage.
| Construction materials: | Cast iron, carbon steel, or stainless steel |
Capacity range: |
Up to 400 gpm |
Speed: |
Up to 1750 rpm |
Differential pressure: |
Up to 250 psi |
Suction lift: |
Up to 15" Hg vacuum while priming |
Viscosity range: |
Up to 10,000 cst |
Temperature: |
Up to 500°F |
Model MD pumps are designed to pump flammable, toxic or ground water polluting liquids, where no leakages can be risked.
MD pumps are typically used for pumping isocyanates, solvents as phenol and xylene, herbicides, pesticides, fungicides, benzene and other hazardous organic liquids including mildly abrasive paints and sweeteners.
Their use is extended to applications where leakage would be costly, e.g. highly refined chemicals, or where long overhaul intervals are required, reducing maintenance labor costs and loss of process time.
