{"title":"Pfeiffer Piston Pumps","description":"\u003cp\u003ePfeiffer dry piston pumps offer a clean, oil-free alternative to rotary vane and scroll pumps for laboratories, analytical instruments and high vacuum systems. Dry piston designs such as the XtraDry use pistons that run without oil in the pumping chamber, and they deliver a low ultimate pressure with very little maintenance and no risk of oil contaminating your process. At Provac Sales, we supply Pfeiffer XtraDry and UniDry piston pumps in new and rebuilt condition.\u003c\/p\u003e\n\n\u003ch2\u003ePfeiffer Piston Pump Models We Carry\u003c\/h2\u003e\n\u003cp\u003eOur Pfeiffer piston pump collection includes:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003ePfeiffer XtraDry 150-2 piston pump, rebuilt, a two-stage dry piston pump for clean vacuum and turbo backing\u003c\/li\u003e\n    \u003cli\u003ePfeiffer UniDry 50SM rotary piston pump; see its product page for the pumping mechanism and specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe XtraDry 150-2 rebuilt is listed with a price, while other models are priced on request.

On the intake stroke, gas is drawn into the cylinder. On the compression stroke, it is pushed out through valves to the next stage or to the exhaust. Two-stage designs, such as the XtraDry 150-2, connect stages in series to reach a lower ultimate pressure.\u003c\/p\u003e\n\u003cp\u003eBecause there is no oil in the pumping chamber and no sliding vane or scroll tip seal, a dry piston pump can run for long periods between services. The main wear items are the piston rings, seals and valves.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose a Pfeiffer Dry Piston Pump?\u003c\/h2\u003e\n\u003cp\u003eDry piston pumps are chosen for several reasons:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eCompletely oil-free pumping chamber, ideal for clean applications\u003c\/li\u003e\n    \u003cli\u003eLow ultimate pressure for an oil-free roughing pump\u003c\/li\u003e\n    \u003cli\u003eLong maintenance intervals and simple servicing\u003c\/li\u003e\n    \u003cli\u003eGood tolerance for continuous operation\u003c\/li\u003e\n    \u003cli\u003eQuiet running compared with many oil-sealed pumps\u003c\/li\u003e\n    \u003cli\u003eNo oil changes, exhaust mist or oil disposal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese advantages make piston pumps especially popular as backing pumps for turbo pumps in analytical instruments and surface science systems.\u003c\/p\u003e\n\n\u003ch2\u003eHow to Choose a Pfeiffer Piston Pump\u003c\/h2\u003e\n\u003cp\u003eConsider these factors:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eRequired pumping speed and chamber volume\u003c\/li\u003e\n    \u003cli\u003eUltimate pressure needed, especially for turbo backing\u003c\/li\u003e\n    \u003cli\u003eWhether the pump will run continuously or cycle often\u003c\/li\u003e\n    \u003cli\u003eGases being pumped, since dry piston pumps are best suited to clean gases\u003c\/li\u003e\n    \u003cli\u003eElectrical supply and motor type\u003c\/li\u003e\n    \u003cli\u003eInlet and exhaust connections\u003c\/li\u003e\n    \u003cli\u003eNoise and vibration limits in the lab\u003c\/li\u003e\n    \u003cli\u003eSpace and weight constraints\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSend us your application details and we will help you compare piston, scroll and diaphragm options.\u003c\/p\u003e\n\n\u003ch2\u003eApplications for Pfeiffer Piston Pumps\u003c\/h2\u003e\n\u003cp\u003ePfeiffer XtraDry and UniDry pumps are used in:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eBacking Pfeiffer HiPace turbo pumps in research and analytical systems\u003c\/li\u003e\n    \u003cli\u003eMass spectrometers and electron microscopes\u003c\/li\u003e\n    \u003cli\u003eLoad locks and transfer chambers\u003c\/li\u003e\n    \u003cli\u003eSurface science and thin film research\u003c\/li\u003e\n    \u003cli\u003eLeak detection systems\u003c\/li\u003e\n    \u003cli\u003eClean laboratory vacuum where oil is not acceptable\u003c\/li\u003e\n    \u003cli\u003ePumping stations built around turbo pumps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003ePiston Pumps vs Scroll and Diaphragm Pumps\u003c\/h2\u003e\n\u003cp\u003eAll three are oil-free, but they suit slightly different needs:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eA \u003ca href=\"https:\/\/www.provac.com\/collections\/pfeiffer-scroll-pumps\" style=\"color: blue; font-family: 'Open Sans', sans-serif;\"\u003ePfeiffer HiScroll pump\u003c\/a\u003e offers high speed, quiet running and a compact footprint, with tip seals as the main wear item\u003c\/li\u003e\n    \u003cli\u003eA Pfeiffer MVP diaphragm pump is smaller and lower in cost, but reaches higher pressures and lower speed\u003c\/li\u003e\n    \u003cli\u003eA Pfeiffer dry piston pump reaches a low ultimate pressure with long service intervals, which suits continuous turbo backing and clean systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor heavy-duty industrial roughing with oil, an Edwards Stokes rotary piston pump is a very different machine, built for furnace and coating duty.\u003c\/p\u003e\n\n\u003ch2\u003eMaintenance Tips\u003c\/h2\u003e\n\u003cp\u003eDry piston pumps need little routine attention, but these practices extend service life:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eKeep the inlet protected from dust and particles with an inlet filter\u003c\/li\u003e\n    \u003cli\u003eAvoid pumping condensable vapors without a trap, since liquid can damage rings and valves\u003c\/li\u003e\n    \u003cli\u003eGive the pump clear airflow to prevent overheating\u003c\/li\u003e\n    \u003cli\u003eWatch for rising ultimate pressure, slower pump-down or new noises\u003c\/li\u003e\n    \u003cli\u003eReplace piston rings, seals and valves using the correct maintenance kit when performance drops\u003c\/li\u003e\n    \u003cli\u003eRecord baseline performance when the pump is new or freshly serviced\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMaintenance kits for the XtraDry 150-2 and related models can be sourced on request.\u003c\/p\u003e\n\n\u003ch2\u003eNew vs Rebuilt Pfeiffer Piston Pumps\u003c\/h2\u003e\n\u003cp\u003eA rebuilt XtraDry 150-2 is an economical way to replace a worn pump in an existing station or instrument, keeping the same footprint and connections.

In 2010 the company acquired Adixen, the former Alcatel Vacuum Technology business, which is why many Alcatel and Adixen designs now carry the Pfeiffer name. Pfeiffer's dry piston pumps extend that oil-free portfolio for users who want long service intervals and clean backing vacuum.\u003c\/p\u003e\n\n\u003ch2\u003eIs a Dry Piston Pump Right for Your Lab?\u003c\/h2\u003e\n\u003cp\u003eA dry piston pump makes the most sense when you need clean vacuum, a low ultimate pressure from an oil-free pump and long periods between maintenance, such as continuous turbo backing on an instrument that runs around the clock. If your work involves frequent solvent loads, a chemically resistant diaphragm pump may suit better. If you need very high speed in a small footprint, a HiScroll may be the stronger option. We are happy to talk through the trade-offs for your system.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eIs the XtraDry 150-2 suitable for backing a turbo pump?\u003c\/h3\u003e\n\u003cp\u003eYes. The XtraDry 150-2 is often used to back turbo pumps in clean high vacuum systems.
