Principles of Operation

E2 2” Flap Valve Pump

Value of Flap Valve Pumps (Top Suction / Bottom Discharge)
Top Suction and Bottom Discharge

Example 1: Gravity assists the passage of suspended and non-suspended solids through the pump.

Example 2: Elimination of pump damage due to settling solids in intermitted applications. Solids settle in the discharge elbows and are flushed out of the pump on start up without the damage that can occur with ball valve pumps on similar applications.

Value of Flap Valve Pumps (Flap Checks vs. Ball Checks)
Flap Check vs. Ball Checks
Maximum solids passage: Flap valve pumps can pass significantly larger solids than like sized ball valve pumps.

Features and Benefits

Top suction bottom discharge (Gravity assistance / Settling solids)
Robust flap valves (Large solids passage, good suction lift)
Rugged clamped construction (Easy assembly and disassembly)
ATEX compliant (Safe / No barrier to market)
Extended life diaphragm options (Versa-Dome and Versa-Rugged)
On/Off/On air system reliability (Elima-Matic air system)
Rugged steel foot brackets (Excellent for mining and mobile applications)
Repair parts consistency (Many “like” parts with standard ball valve units: Air section, diaphragms, diaphragm plates, and valve seat seals)
Abrasion resistant wetted castings (Sand cast aluminum castings and stainless steel flap seats and retainers offer superior abrasion resistance)
