Series G - Specification Options
Listed below are optional component configurations that can be used to enhance the operation of the Series G pump.
Series G pump casings may be supplied fitted with hardened, replaceable wear plates (standard on sludge pumps). The wear plates can be replaced with minimal pump dismantling and without removal of pump from service.
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.
Pump casings are supplied with integral cast flanged inlet and outlet connections to all major standards including ASA/ANSI150, BS4504/DIN2533, BS10E and more.
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
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.
