Positive Displacement Pump

Product Details:

• An AODD pump is a type of positive displacement pump that uses compressed air as a power source.
• The compressed air is shifted from one chamber to the other by a linked shaft that allows the chambers to move simultaneously.
• This back-and-forth motion forces liquid out of one chamber and into the discharge piping while the other chamber is being filled with liquid at the same time.
• These pumps use reciprocating elastomeric diaphragms and check valves to pump fluid.
• The liquid chambers are filled and emptied by fluid that is drawn through a common inlet and discharged through a single outlet.

• No electrical motor - non sparking.
• No mechanical seals or gland packing.
• The pumps can run dry indefinitely without damage.
• Safe for use in hazardous / explosive environments.
• Variable flow - simply regulate the inlet air supply to adjust the pump flow from zero to max.
• If discharge is clogged or closed pump stops immediately; no power consumed, no wear. By opening discharge, flow starts automatically.
• Self-priming from a dry start up to 6 meters without a foot valve.
• Operates submerged or with flooded suction.
• No close fitting, sliding or rotating parts so can handle a wide range of fluids with high solid content.
• Gentle non-shearing action.
• Quick assembly and disassembly with split clamp bands.
• Pumps are light weight and portable.

Product Details:

• Boerger is synonymous for Rotary Lobe Pump.
• The simple and ingenious principle of a self-priming, valveless positive displacement pump found its marketplace in all industries.
• 17 pump models in five series build the base for your individual pump application.
• The variety of components and materials of construction enables Boerger to supply an optimized pump to each customer.
• Rotor shapes and / or tips, elastomer coatings, shaft seals and materials of the pump casing and protection plates are all chosen depending on the pumped fluid.
• Boerger Rotary Lobe Pumps are constructed following our MIP design criteria.
• MIP (Maintenance In Place) ensures optimum maintenance friendliness.
• All fluid wetted parts can be quickly maintained and replaced when necessary by your own staff – without the removal of pipe or drive system.
• The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive.
• This vacuum draws the liquid into the pump chamber.
• With further rotation, the pumped medium is conveyed past the pump wall into the pressure area.
• Up to six chamber charges are displaced with each drive rotation - depending on the rotor type.
• When the rotor is at a standstill, the pump seals off almost completely.

• Easy

Product Details:

• It is a positive-displacement (PD) pump that use one or several screws to move fluids or solids along the screw(s) axis.
• In its simplest form (the Archimedes screw pump), a single screw rotates in a cylindrical cavity, thereby moving the material along the screw's spindle.
• This ancient construction is still used in many low-tech applications.

• Suitable for various transfer needs
• Optional models to handle solids
• Optional vertical configurations
• Optional mobile configurations
• Low noise
• No emulsified shear
• Low pulsation
• Suitable for wide range of viscosities
• Low fluid agitation
• Direct drive
