{"title":"Edwards Piston Pumps","description":"\u003cp\u003eWhen a process needs rugged, high-capacity roughing vacuum day after day, oil-sealed rotary piston pumps are a proven choice. The Edwards range of rotary piston pumps grew out of the Stokes Microvac line, a name many furnace and coating engineers still use. These pumps are known for heavy cast construction, tolerance of demanding duty and long service life when maintained properly. At Provac Sales, we supply Edwards 412J and 612J piston pumps and rebuild several Edwards and Stokes piston pump series in house.\u003c\/p\u003e\n\n\u003ch2\u003eEdwards Piston Pump Models We Carry\u003c\/h2\u003e\n\u003cp\u003eOur Edwards piston pump listings include:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eEdwards 412J rotary piston pump, a single-stage pump widely used for industrial roughing and backing large boosters\u003c\/li\u003e\n    \u003cli\u003eEdwards 612J rotary piston pump, a larger model for higher gas loads and bigger chambers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe also repair and rebuild Edwards 148, 149, 212 and 412 series piston pumps. If you have an older Stokes or Edwards piston pump, send us the model and serial number and we will check rebuild options or a suitable replacement.\u003c\/p\u003e\n\n\u003ch2\u003eHow a Rotary Piston Pump Works\u003c\/h2\u003e\n\u003cp\u003eA rotary piston pump uses an eccentric cam on a shaft to drive a piston inside a cylindrical stator. As the shaft turns, the piston sweeps around the stator, drawing gas in through an inlet slide valve and pushing it out through an exhaust valve. Oil seals the clearances, lubricates the moving parts and carries away heat.\u003c\/p\u003e\n\u003cp\u003eCompared with a rotary vane pump of similar size, a piston pump has fewer sliding sealing surfaces and heavier components. That design gives it a high displacement in a robust package and makes it tolerant of the dust, vapors and thermal cycling common in industrial processes.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose a Piston Pump?\u003c\/h2\u003e\n\u003cp\u003eRotary piston pumps remain popular for several reasons:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003eHigh displacement for large chambers and fast pump-down\u003c\/li\u003e\n    \u003cli\u003eDurable construction suited to continuous, around-the-clock duty\u003c\/li\u003e\n    \u003cli\u003eTolerance of particulates and process contaminants that would damage lighter pumps\u003c\/li\u003e\n    \u003cli\u003eProven performance as backing pumps for large mechanical boosters\u003c\/li\u003e\n    \u003cli\u003eLong life with straightforward rebuilds when wear eventually occurs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe trade-offs are size, weight, vibration and oil management.
