The Range The API 676 range is based around the proven double helical gear pump design and benefits from its inherent reliability and efficiency. By employing modular design, the central mounting arrangement can accommodate either electric, hydraulic or air motors and d ifferent capacity pump ends. The foot-foot design incorporates spacer couplings that allows for the mechanical seal to be serviced without removing the pump or the need for re-alignment. All units c ome supp lied on either a slab basep late or a fab ricated hollow basep late ready to be grouted in place.
Design Varley designs by using soild models in Autodesk Inventor. These can be used by the system designers to agree space and c onnection constraints.

Pumping Principle The pump contains two or three double helical gears that run on fixed centres. The rotary action of the driver gear is transferred to the driven gear at the gear mesh line. As the gear has a 30deg helix angle, there are multiple meshes per shaft revolution, compared to the single mesh of a spur gear p ump. These multiple mesh’s give the output fluid a smoother pressure ripple. The rotary action of the gear causes a depression in pressure within the tooth form, which draws fluid into the gear tooth. When the tooth rotates to one revolution to the discharge side of the pump, the mesh line acts as a seal and forces the fluid into the discharge port. The only part of the pump that is subject to discharge pressure is the discharge port. Each shaft is supported by full complement roller bearings on either side of the gear and selected to give the highest possible Lb10 life.
Ancillaries Pump ancillaries are chosen from reputable suppliers such as ABB, Birkett, Baily, Crane, Fluiten and Burgmann, ensuring that the valve, motor or seal meets or exceeds the projec t requirement.
Pump Performance Indication Guide It is advisable to check the application with our works before making final selection. Table is based on oil having a viscosity of 75 sec's Redwood No.1.
