Versa-Matic's E2 2" pump uses the Elima-Matic air valve system to provide non-stalling, lube-free performance. It is available in a clamped or bolted design, with some models offering a side discharge feature that prevents corrosive fluid from leaking onto the pump's center section.
- is available in either plastic or metal
- avoids blow-by when the pump is online but not in use
- is self-priming
- provides dimensional interchangeability with Wilden 2" pumps
- offers horizontal discharge model on bolted metallic pump
Elima-Matic's non-stalling, lube-free air valve system allows the Versa-Matic E3 3" pump to provide reliable performance. Available in clamped or bolted models, with leak-free design that reduces downtime and ensures continuous operation.
- is available in either plastic or metal
- can handle infinite variable flows up to 90% solids
- is self-priming
- provides dimensional interchangeability with Wilden 3" pumps
SIZE 2" METAL FLAP VALVE AND HIGH PRESSURE DOUBLE DIAPHRAGM PUMP
Flap valve VERSA-MATIC pumps are especially recommended for slurries and liquids with suspended solids. Flap-valves allow passage of suspended line-size solids without damage. Variable discharge porting options available on the 1" pump model.
Mating Surfaces All Yamada pumps incorporate bolted construction, which eliminates leaks and simplifies reassembly after maintenance. Many competitors utilise clamp band construction, which frequently requires frustrating and unnecessary rebuilds due to leakage from misalignment during reassembly.
Outside Accessible Air Valve Inspection or maintenance of every Yamada air valve may be performed without removing the pump from service.
Pilot Valve Unique to the Yamada design is an individual modular pilot valves that actuates the air valve. It is depressed slightly by the inner centre disk creating a pressure drop at one end of the air valve, allowing shifting to occur. It is maintenance free with no cumbersome snap rings or lubricated dynamic o-rings to replace or repair.
Diaphragm Dynamics Extensive research had led to the development of an optimal stroke length that maximizes diaphragm, like and performance while minimizing downtime and maintenance costs.
