Tuthill Corporation - Tuthill Vacuum & Blower Systems products

Simple, robust design can handle process by-products – liquids, condensate, and even small particles. No oil or water in contact with process. No contact between operating components in the casing. Full pumping speed from atmospheric pressure down to 1 Torr; ultimate pressure 0.1 Torr (.05 Torr on Model KDP-800). Quiet operation – less than 85 dB(A). Short gas path through the pump for quick discharge. Extended shaft for either V-belt or direct drive. Casing and rotors are made of ductile iron, PFA coated.

Ideal for pumping wet gas mixtures at low pressures. Oil-filled systems avoid problems with corrosive contaminants and sealant liquid vapor pressures at higher temperatures. Process liquid-filled systems prevent contamination of process gases with either water or oil. A variety of two and three-stage systems are available, complete with instrumentation, condensers, partial or complete sealant liquid recovery and recirculation, piping, and valves.

Combine high pumping speed with deep vacuum levels and operate free of oil, water or other sealing liquids. Flows range to 4,500 CFM (7646 m3/h) with vacuum levels to 10 microns and below Complete engineered solutions are available and may include any combination of dry screw vacuum pumps, vacuum boosters, electric motors, direct of V-belt drive, coolant recirculation  systems, instrumentation, controls, skid piping and valves.

Pump high volumes at very low pressure. High-capacity dry rotary lobe vacuum booster is matched to a smaller rotary piston vacuum pump. For continuous operation below 1 Torr (1.3 mbar a), the vacuum booster can increase pumping speed by a factor of 10 or more. For operation at higher pressure and for faster evacuations, the booster may be approximately twice the capacity of the piston pump. Performance ranges 200-12,000 CFM (340-20,388 m3/h) with ultimate vacuum levels as low as 0.2 microns. Conventional systems with direct driven or V-belt driven boosters. Low-profile systems with close-coupled boosters are available. Creates a higher capacity system with economy of scale. Tuthill application engineers can help you make the best selection for your specific needs.

Ideally suited for pumping wet mixtures. Can pull down as low as 4 Torr (5.3 mbar a). Low-pressure performance is limited by the vapor pressure of the sealing liquid: water, oil or process liquids. Complete engineered system solutions available: instrumentation, controls, piping & valves. Self-contained liquid recovery & recirculation are available. Center-anchored tie rods allow access to either end of the pump without total disassembly. Double mechanical seals available in models KLRC75 through KLRC525 to meet API Piping Plan Requirements.

Recommended for applications where operating pressure is below 0.1 Torr (0.13 mbar). Achieve lowest possible pressures from mechanical pumps. Rugged and reliable. No metal-to-metal contact between pump piston & cylinder - clearances are filled with oil. Unequaled durability, even in dirty applications.

Designed to be interchangeable with equivalent models from competing manufacturers, EQUALIZER DF rotary blowers offer many distinct advantages such as higher pressure capability (18 PSIG on most models), true, drop-in replacement even to the point of matching the port connector bolt patterns, and helical gearing to reduce noise.

CVP Central Vacuum Systems provide a remote supply of plant vacuum which can be located away from the production area or vacuum outlets, thus reducing noise and heat in the work area. The systems feature the “A” Series single-stage liquid ring pumps in either a simplex (one pump) or duplex (two pumps) design. The energy-efficient systems are designed to operate automatically, with the pump(s) starting when the plant vacuum demand increases, and stopping when the demand is met. Vacuum is maintained by means of pressure switches which cycle the pump(s). These systems require only water and electric power connections. A solenoid valve on the seal water line provides water whenever the pump(s) cycle.
