Tandem Diaphragm Pumps

Dec. 17, 2010

KNF NF single-head pumps are now available as tandem diaphragm pumps for liquids.  Two pump heads driven by one motor are uniquely integrated to equip designers with highly versatile solutions for a wide range of OEM applications.  These specially configured self-priming pumps can be specified in a variety of standard materials, connection types, motors, and with custom options to meet exact requirements. They additionally can serve as “drop-in” replacements for other tandem-version pumps, regardless of manufacturer.

NFT pumps join a growing family of KNF diaphragm pumps benefiting from twin-headed pump technology and are available in three sizes: NFT30, NFT60, and NFT100.  All run quietly, smoothly, efficiently, and reliably over time without maintenance and, depending on model, KNF tandem pumps can achieve flow rates of 1.2 lpm per head and pressure up to 85 psig per head.  They ideally suit applications ranging from medical devices and chemical/blood analyzers to large-scale inkjet printers and other equipment and instruments across industries.
The tandem configuration delivers multiple benefits for end-users.  Both sides can perform independently to handle different liquids (or even air/gas on one side) along with separate pressure and flow requirements or they can be plumbed in parallel to operate together for increased flow and reduced pulsation.

NFT pumps can be selected either with brush-commutated DC, brushless DC (BLDC), or ironless core motor.  The consolidated single motor and two-headed pump design promotes overall cost savings and creates a compact footprint to minimize space requirements.  Pumps can be mounted for operation in any position.
