FOUR SERIES DIAPHRAGM GAS PUMPS USE INNOVATIVE DRIVE TECHNOLOGY
Previously only available as a project option, KNF has launched four compact pump se‑ ries that are using new DC‑BI motor technology. The new KNF Direct Current Brushless Integrated (DC‑BI) technology drives the four new series NMP 830 DC‑BI, NMP 830 HP DC‑BI, NMP 850 DC‑BI, and NMP 850 HP DC‑BI. For the first time, the motor is integrated directly into the pump hous‑ ing, with an expected lifetime of over 20,000 h. In addition to their mechanical advantages, the use of an advanced, proprietary BLDC motor is said to enable parameterization such as speed range, starting behavior, control characteristics or thresholds. Depending on the specific series, the new pumps achieve a flow rate of up to 7 l/m, an ultimate vacuum of down to 220 mbar and a maximum pressure of up to 3 bar.

WIRELESS SYSTEM FOR REMOTE ACCESS TO MEASUREMENT DATA
Krohne has introduced the Optibridge 3880 IIoT data logger for remote data services, acquisition, and evaluation. It is a fully autonomous, bat‑ tery‑ or grid‑powered wireless communication system for remote access to measurement data, aimed at the water and wastewater industry. Using mobile communication via 2G, 3G and 4G, the unit offers a wide range of remote data management options — from simple data logging to internet connectivity and storage for maintenance, process visualisation and data evaluation. Using supplied integra‑ tion software, data can also be integrated into SCADA or other software systems by using such as OPC UA, and CSV. The customer has full control over their data, the company says, as it is hosted on their own local server and send with end‑to‑end encryption.
Lutz Pumps has introduced the model TR3 flow meter. Available in polypropylene or PVDF, the unit mounts on all drum and container pumps, the company says. The symmetrical measuring chamber allows it to be used for all flow directions and measures low‑viscosity, non‑flam‑ mable media, the company says. PP units are suitable for neutral and aggressive media.
The Rubbermaid model H‑479, 400 lb.‑rated digital receiv‑ ing scale from Uline features a remote, ½ in. LCD display with a wall mounting bracket and 9 ft cord for reading in both pounds and kilograms from any angle. The remote design is suitable for weighing larger objects that might otherwise cover up the readout. In addition, the scale’s tare function, which removes the weight of a container be‑ fore weighing, it is also suitable for that need to weigh up food produce and other ingredients. The receiving scale’s 12 x 12 in. platform has a durable, non‑skid grid design to prevent packages from slipping off. The scale can be pow‑ ered with either a 110 Vac adapter (included) for frequent sustained use or a 9 Vdc battery (sold separately) if the scale requires moving to a different location for use. An au‑ to‑off feature helps reduce battery usage.
