Pump technology has come a long way in the last ten years, with new features allowing for stronger performance than ever before. With such big strides in functionality, it may be time to consider upgrading your pump. Even if your current pump solution is still working, a new pump might provide substantial performance improvements. While it may seem intimidating, the process of upgrading can be simplified with help from your pump partner. KNF’s engineers work directly with customers to make the upgrading process easy and efficient. New Line of KNF BLDC Motors Provide Unprecedented Parameterization and Control BLDC motors provide advantages in a variety of applications. They are ideal for medical applications, where additional control makes it possible to adjust the motor speed during high and low periods of operation. This parameterization is also critical in roughing pump applications. These pumps need to start quickly reaching a certain level and then being slowed to their operational speed, a process that is simplified with BLDC motors. KNF BLDC Motors Are Available on a Wide Range of Gas and Liquid Pumps Both gas and liquid diaphragm pumps can be fitted with BLDC motors for additional parameterization and control. The N 938.1.2 is among those available with a BLDC motor. It provides a maximum flow rate of 53 l/min with maximum pressure of 1 bar (rel.) and a maximum vacuum of 140 mbar (abs.). The N 938.1.2 is one of several pumps available with a BLDC motor. These specialized motors allow for precise control and digital parameterization. Many liquid diaphragm pumps are also available with BLDC motors. NF series pumps, including the NF 60, offer strong performance along with the control and precision provided by this new motor technology. The NF 60 offers a maximum flow rate of 0.6 l/min with maximum pressure of 1 bar (rel.) and a maximum suction height of 3 mH2O. It has a compact design while offering excellent performance and is a strong choice for those looking to upgrade their liquid diaphragm pumps. Smooth Flow a Game Changer in Limiting Pulsation Inkjet printing is another area where upgrading to a Smooth Flow pump should be considered. Smooth Flow technology can increase efficiency in inkjet systems and also reduce pressure peaks, preventing disruptions in print quality. It minimizes cavitation, maintaining the integrity of the ink. It can also reduce resistance in tubing and move liquids such as inks and varnishes smoothly. Smooth flow pumps eliminate the need for external dampeners in inkjet systems, substantially reducing complexity, cost, and size. These are just a few of the applications where smooth flow pumps provide performance advantages. KNF Offers a Variety of Smooth Flow Options KNF offers several options for those looking to upgrade to a Smooth Flow pump. The FP series of liquid diaphragm pumps offer Smooth Flow technology along with the traditional advantages of diaphragm pumps. They offer excellent reliability, contamination free transfer, are oil- and maintenance-free, self-priming, and can run dry. Pumps like the FP 70, with a maximum flow rate of 0.7 l/min, maximum pressure of 2 bar (rel.) and a maximum suction height of 3 mH2O, are strong choices for a variety of applications where Smooth Flow technology is desirable. KNF’s FP 70 liquid diaphragm pump is one of several options for those looking to upgrade to a pump with Smooth Flow technology.
