Hydraulics & Pneumatics October 2022

HYDRAULICS A new miniature positive displacement pump with integrated control electronics which offers a high level of flexibility in a small, lightweight package, is the latest development from miniature fluid control specialist The Lee Company. Minimising size and maximising performance with leading fluid control technology is Lee’s speciality and this new pump expands the established range of miniature radial piston designed displacement pumps. The pump enables users to exploit the benefits of self-priming 30 HYDRAULICS & PNEUMATICS October 2022 www.hpmag.co.uk Pump and Motor Division Europe (PMDE) of Parker Hannifin has launched a new variable displacement, bent-axis motor series, V16. The new V16 is an evolution of the established V12 and V14 motor series, and offers high speed performance and pressure ratings, resulting in increased productivity and higher safety margins in construction, marine & offshore, oil & gas, and agriculture applications. The motors are available in two sizes, V16-220 and V16- 270, and are designed for both open and closed-circuit transmissions with a focus on high-performance machines. Due to the V16’s differential piston control system, along with a 3-way valve and best-in-class displacement ratio (5.5:1), the V16 offers smooth and precise control. The patented spherical piston design with laminated piston rings provides a high shaft speed capability, up to 30% higher than competitors. In combination with the high-pressure level, up to 550 bar, the V16 offers enhanced performance and long service life. High volumetric efficiency of up to 99% The spherical piston design is also claimed by Parker to enable high volumetric efficiency of up to 99%. With the ability to downstroke motors to zero-displacement and idle, significant fuel savings can be achieved. “The new V16 is probably the most efficient variable bent-axis motor on the market,” states Christian Bengtsson, Product Leader at Pump & Motor Division Europe. “We can significantly reduce operating costs by lowering power consumption and support OEMs’ goals to reduce emissions and comply with future environmental regulations.” The V16 is available in both ISO and SAE versions along with flexible porting options, including standard axial and radial ports. Parker also offers monitoring with the addition of a new position sensor and plug-in speed sensor. Parker Pump & Motor Division Europe (PMDE) offers solutions that can help customers build better and more productive machines. With this mission in mind, PMDE designed the Customer Service Program to supply customers with the right system or component at the right time – no matter whether working directly with Parker, or with one of its premier distributors. Parker Hannifin is a Fortune 250 company that offers cutting-edge motion and control technologies. For more than a century, the company has been enabling engineering breakthroughs that lead to a better tomorrow.

In addition, intelligence is built into the pump module to provide operational feedback such as pump speed, motor current and fault monitoring. Suitable for harsh environments Due to their qualification to numerous aerospace specifications, applications would typically be wherever miniature fuel pumps need to withstand the harshest environments that aerospace fuel systems are exposed to. In addition to fuel transfer, other applications would be: in unmanned aerial systems, auxiliary power units, generators, lubrication and cooling systems. Performance and features include: a high-efficiency brushless DC servo motor running on 12-36 VDC supply voltage, operating temperatures ranging from 4degC to 100degC, pressures up to 100 psid, flows up to 235 pounds per hour (0.52 USGPM). They are compatible with most fuels and petroleum-based fluids to ensure high performance and quality in a small, lightweight package. www.theleeco.com
