New Inline Four-Pump Drive for Construction, Mining & Oil Field Equipment Applications

Durst has released a new four-pad pump drive especially designed for applications where space is limited. With its low profile and excellent torque-carrying capacity, the 4PD10L delivers a high-performance, cost-effective drive solution in construction, mining and oil field equipment.

The 4PD10L features an inline output configuration with 10.5" gear centers. The drive incorporates a simple, one-piece design, based on Durst’s popular modular format, for easier assembly and installation. It has a maximum torque rating of 1,995 lb-ft.

The 4PD10L, which meets SAE and AGMA standards, measures 8.12" deep x 16.5" high x 37" wide. The compact size is adaptable to trenchers, mining trucks, underground mining equipment and other applications where tight engine compartments would rule out a standard four-pad arrangement. Space-saving solutions like that offered by the 4PD10L are of particular interest to oil field OEMs.

The 4PD10L is compatible with any SAE pump shaft and can be used as a drop-in replacement for other manufacturers’ drives.

Like the entire line of reliable Durst pump drives, the 4PD10L runs cooler, lasts longer and is simpler to service. The class 10 spur gears run on heavy-duty ball bearings. The internal spline enables quieter operation. Bearings and gears are self-contained within the housings. Durst’s patented pump pad design keeps oil constantly flowing through the bearings and provides for wet spline operation, even at startup.

Pump pads and input adapters can be easily changed without disturbing bearings. Thanks to the single seal, bearing, gear and adapter group design, there are fewer parts to inventory.

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
