 | Bellows pumps
Bellows metering pumps operate on a positive displacement principle. Pumps are designed to displace both corrosive and noncorrosive fluids. Accurate to ± 0.5% from stroke to stroke, when pump is set 50% to 100% of full stroke. Discharge pressure is maintained over the entire flow range of the pump. Poppet valves are utilized to prevent backflow; and springs are available to provide a positive shutoff, preventing siphoning through the pump in applications where a positive suction head exists. |
|  | Compact Bellows
Compact models were designed for applications with low pressure requirements. Maximum discharge pressure to 5 psi. Pumps are only available with the standard crank mechanism. Pumps with up to 4 bellows modules are available. Flow rate of each bellows module is independently adjustable. |

 | Mini Bellows Pumps
Mini bellows models are ideal for low flow, low pressure metering applications. The pump is constructed entirely of plastic The pump utilizes GRI's time-proven bellows technology to provide an accurate chemically-resistant metering pump with a long life, at an economical price. |
|  | Oscillating Pumps
Oscillating pumps are self-priming, corrosion resistant, Oscillating pumps have no dynamic seals and are constructed from FDA accepted materials. Typical applications include film and microfilm processors; litho and graphic arts plate processors; detergent dispensing, chemical mixing, medical, scientific and laboratory equipment. These pumps are intended for replenishing, transfer and circulating installation Features: Self-priming No dynamic seals Compact, Lightweight and EconomicalCan operate continuously Moisture & corrosion resistant coil Outlet valve styles: Poppet – prevents backflow thru pump 2-Piece – allows higherflow, no backflow prevention Spring Styles Leaf Spring – extremely quiet Coil Spring – higher flow & efficiency, greater priming ability |
