Air Operated Diaphragm Pumps JOHNSON PUMP

Reduced pulsatio Johnson Pump has solved the problems inherent in conventional AODD pumps. How? With revolutionary new technology that we have incorporated into our latest innovation – OptiFlo.

The five steps to our unique AODD solution Step 1: Develop a new non-stalling air motor that Step 4: Develop a flexible diaphragm suspension, works with all types of air – dry, moist, dirty or oily – without icing problems. which eliminates “dead ends” and gives lower pulsation. Step 2: Invent a new type of air valve – an ingenious Step 5: Replace the usual noisy ball valves with flap pneumatic device that switches the distribution of air between the air chambers in a fraction of a second. valves, thereby reducing pulsation and improving the suction capability. Step 3: Design a central flow path,...

The OptiFlo way Central flow in OptiFlo Peripheral flow in a conventional AODD pump AODD pumps haven’t really changed much over the years. The basic design has remained the same. Until now! With OptiFlo, Johnson Pump can introduce a new way of thinking. Johnson Pump has invested a lot of time in product development, searching for innovative solutions to existing problems. Radical new concepts, much imagination and several patented inventions were needed. The result? A compact and robust AODD pump with lower pulsation that works silently and gives better performance at a lower life cycle cost....

A closer look inside OptiFlo clearly shows why, in every respect, OptiFlo is a completely breakthrough in AODD pump design. A design that is simple and compact, yet full of new patents and smart solutions. Instead of forcing the fluid round four transverse directions, OptiFlo pumps it straight through on a central flow path. This reduces hydraulic losses and gives a stronger, even flow. The principle is simple – straightforward is best! The new self-cleaning and non-stalling pneumatic air motor works with any kind of air — dry or moist, dirty or oily. The patented Flexible Diaphragm Suspension...

Can be opened in next to no time A complete air motor with no mechanical link to the pump unit. It can be inspected and serviced without dismantling the wet parts. With the silencer replaced by a hose, OptiFlo becomes a simple submersible pump. The heart of the air motor, the FPV (Frictionless Pivoting Valve), is easily accessible. The pump can be opened for inspection or service in just a few minutes. Diaphragms are not fixed to the shaft, allowing quick and easy replacement. Inlet and outlet checkvalves, seats and shaft can be changed after loosening a few screws. OptiFlo is very easy to install...
