ZENITH PLANETARY
The Zenith Planetary pump series supports manufacturing operations melt fiber production maximizing yields and run times. Planetary metering pumps provide multiple output streams in a compact pump design. These pumps are ideal for fixed displacement applications requiring 2 or more outputs.
Available Capacity Range: 0.4 – 6.0 cm^3/rev/port. Max Operating Temperature: 644F (340C). Max Pressure Differential: 7,200 psi. Max Viscosity: 500,000 cps
Since 1926, Zenith Pumps has provided the man-made fiber industry with precise, pulseless and repeatable gear metering pumps. From the earliest applications in viscose and hot-melt fiber spinning, through the more recent applications in high performance, specialty fibers, Zenith Pumps has met the challenges of the fiber industry with pumps of unmatched performance and quality.
As the largest spin pump supplier to the world’s leading fiber producers, Zenith Pumps has remained in the forefront of gear pump developments
through ongoing programs of research into both pump design and precision part manufacturing. In addition, Zenith Pumps is committed to providing superior quality and customer service with two state-of-the-art, ISO certified production facilities fully integrated to ensure that our fiber producer cus- tomers have a reliable source of supply for their critical gear pump needs. Our customer support efforts are further enhanced by a worldwide network of direct offices, service facilities and sales representatives to respond to the demands of the fiber industry.
Planetary Pumps For Textile Denier Melt Fiber Spinning
The planetary pumps described in this catalog were developed by Zenith Pumps to maximize melt fiber production yields and run time. The pumps are available in configurations with 2, 3, 4, 6, or 8 metered outlet streams per pump and in displacements covering the throughput range of 0.1 to 8 liters/hour per stream. When properly installed and operated, the spin pumps provide the fiber producer the following important benefits.
Outstanding stream to stream and pump to pump metering uniformity resulting from superior design, quality and wear resistance.
Reduced polymer shear and down- stream thermal gradients resulting from optimized gear geometry and internal flow paths.
Superior pump pressure capability resulting from high strength components including a full diameter coupling housing plate.
Superior pump toughness and durability resulting from through hardened, particle metallurgy components.
In addition to these benefits, the single gear level planetary pump models offer greater stream to stream process temperature uniformity result- ing in improved yarn consistency and processability as compared with multi gear level style pumps.
