Pumped Media Seals

The optimum primary seal can be chosen to match the pumped media and duty conditions. Single or double mechanical seals include flushed or aseptic variants. For arduous duties hard faced seal materials such as tungsten carbide or silicon carbide can be used. A wide variety of commercially available mechanical seal options including single and double cartridge seals are available for sludge and other difficult applications. Packed glands offer a simple, low cost, and easy to maintain controlled leakage sealing arrangement. Pumped media wetted elastomers are EPDM, NBR, FPM all FDA conforming or PTFE for chemical applications.

Connections

Pump casings are supplied with integral cast flanged inlet and outlet connections to all major standards including ASA/ANSI150, BS4504/DIN2533, BS10E and more.

Rotor Materials

For increased abrasion resistance pumps may be supplied with NBR covered (models G7-0550-H07 and G8-0745-H10 only) or urethane rotors. The urethane rotors can be supplied slotted, providing grit channels to improve
rotor life.

Surface Finish & Coatings

For abrasive applications the pumphead and rotors may be supplied with a tungsten carbide coating or other surface hardening treatment to increase wear resistance.

Increased Pressure Rating

Alternative higher strength shaft materials will enhance pressure ratings.

• 145 psi for pump model G7-0550-H07
• 100 psi for pump model G8-1149-H03

Motorized Pump Units

Series G pumps may be supplied fully motorized with fixed or variable speed drives including appropriate control systems if required, mounted on either mild steel or stainless steel baseplates. In addition to electric motor drives, hydraulic, pneumatic, diesel or gasoline powered prime movers can be fitted.
