Diaphragm Pumps
All-Flo Pumps

All-Flo Pump’s s a leading manufacturer of Air Operated Double Diaphragm pumps and fluid handling solutions and are made from the widest range of metallic and plastic materials.

HOW AN AIR OPERATED DOUBLE DIAPHRAGM PUMP WORKS

The air-valve uses pressurized air to move the diaphragm on the left outwardly. The left diaphragm and right diaphragm are connected by a diaphragm rod. When the left diaphragm moves to the right it causes the right diaphragm to also move to the right.

When the diaphragm on the left side moves to the right, it is referred to as the suction stroke. When in its suction stroke it causes the left suction ball to move upward opening and the left discharge ball to move downward closing. This creates suction in the left chamber pulling in liquid.

When the diaphragm on the left side moves to the left, it is referred to as the discharge stroke. When in its discharge stroke stroke it causes the left suction ball to move downward closing and the left discharge ball to move upward opening. This causes the liquid to leave the left side of the pump.

While this process is happening on the left side the opposite stroke is happening with the right diaphragm. This alternates the suction / discharge strokes back and forth between the sides as long as compressed air is being supplied to the system.

HEAVY DUTY METALLIC PUMPS

All-Flo metallic diaphragm pumps are available in aluminum, anodized aluminum, and stainless steel. Pumps in aluminum and anodized aluminum offer medium corrosion and abrasion resistance, while stainless steel is suitable for applications that require higher chemical and abrasion resistance.

Batch Controllers

Batch controllers are available in two basic configurations. A handheld unit is locally controlled and programmed for individual batching and dispensing operations. The Model 420 controller is engineered to provide speed control of a solenoid-controlled pump that is linearly proportional to an external 4-20 ma signal. Available in 12VDC, 24VDC, 120VAC or 220VAC and utilize a standard DIN 43650B or DIN 43640C connector, depending on the pump size. In addition to solenoid control, cycle counters are available on all pumps.

Filter Regulators

Available in ¼ inch, ½ inch, & ¾ inch for use with all sizes of AODDs to control pressure and regulate speed.

Drum Pump Kits

Pump kits are available for all ¼ inch, 3/8 inch, ½ inch and 1 inch pumps andallow for the convenient transfer of fluids from a 55 gallon drum. Each kits is make of compatible material and comes with a 40 inch tube (for maximum fluid transfer) and a bung adaptor (for connection to the drum.
