Versa-Matic air-operated diaphragm pumps have a robust leak-free bolted design which reduces maintenance downtime and are self-priming to handle solids up to 3 inches. These units provide an an ideal combination of flow, size and portability as compared to other pump models, with a maximum flow rate of 163 gpm (617 lpm). They further feature the patented Elima-Matic air valve system for a no stalling, lube-free performance and are available in 1/4 inch, 3/16 inch and 3/8 inch diameter variants on Raptor Supplies.
Yes, these pumps can easily handle solids, slurries and suspended solids in various mixtures & viscosities.
These double diaphragm pumps can run dry as they do not rely on mechanical seals. Instead, they employ diaphragms to pump the liquid back and forth.
Since these pumps are air-operated and do not require electricity for operation, they are safe for potentially explosive environments like mines.
Yes, as soon as the discharge pressure exceeds the air input pressure, the pump stops cycling. The pump restarts once the discharge side pressure is released.
