- Identify suction and discharge check valves, including single/double and ball/cone execution. [source]
- Identify both hose diaphragms and their installed size/material record. [source]
- Record piston and piston-seal service items on the hydraulic side; the double hose diaphragm isolates the conveyed medium. [source]
- Identify the leakage-compensation control, head pressure-relief valve and hose-diaphragm monitoring system separately. [source]
FELUWA MULTISAFE Double Hose-Diaphragm Pumps: Wet-End and Nameplate Identification
OEM examples include TGK 400 – 3 DS 230 (single-acting, three heads) and DGK 500 – 4 DS 350 (double-acting, four heads). Preserve the entire designation including the DS section.
OEM series guide
Identify the installed design before enquiry
FELUWA MULTISAFE pumps use double hose diaphragms activated by a reciprocating piston through hydraulic fluid. The pumped medium follows a linear path through the hose diaphragm and check valves, separated from the pump head and hydraulic area.
