Zenith, Pumps, headquartered in the United States of North Carolina Law State Stanford since 1926, Zenith Pumps has been engaged in the design and manufacture of precision gear pump. Products such as gear pumps, metering pumps, rotor pump services including pump recovery and transformation of product applications, including chemical fiber, injection, extrusion and additives raise. Over the years, Zenith, Pumps as a technology innovator of the gear pump applications, have been a number of industry sectors and broad user acceptance. 
 The 1940s and 1950s, Zenith Pumps initial PEP pump (polymer extrusion pump) design for the extruded film, sheet, and profiles, they are as the basic raw material for polyester and nylon polymer. Since then, Zenith Pumps is actually the pump of the plastics industry as raw material for polymer production. This development process also includes many of the improvements which PEP Series pump, it has a better performance. 
 Unique Zenith, Pumps the PEP pumps pump displacement design, polymer precise and stable transportation and not subject to the impact of pressure, temperature, and viscosity of these conditions change. PEP series pumps provide the pressure in the extruder and die, and can match the parameters of the extruder, the increase in output and tolerance to demanding circumstances, to provide uniform melt. 
 Pumps, Zenith, PEP series pump has become the components of polymer production in the plastics industry are widely adopted, in any need precise, pulseless and repeatable measurement of fluid, Zenith Pumps Company's products can be found. 
 Over the years, the production of the plastics industry, there are many polymer production equipment using the gear pump assisted extrusion to solve all kinds of key issues, Zenith, Pumps Gear pumps are compatible with the extruder, to optimize the entire extrusion process. 
 Extruder, the molten polymer, and make it uniform, Zenith, Pumps pumps provide the required pressure, reduce the work of the extruder, thus reducing the shear heating and the required torque, and the elimination of fluctuations, all of which optimize the extruder performance, and provides the advantage of the following areas: 
 Improved dimensional stability ---- effectively isolate the mold from the upper reaches of the fluctuations. 
 Controlled melting quality --------- adjust the extruder back pressure to reduce the residence time, stability, mastication, and reduce the melting temperature. 
 Increase production ------------- regardless of the requirements to establish the size of the pressure to provide very high efficiency 
 Reduce the use of raw materials --------- provided the final product size changes 
 To eliminate fluctuations and screw shocks ----- effectively solve the problems caused due to the melt density or extruder parameters 
 Enhance the flexibility of the extruder ----- allowed to change processing, such as: high back to the amount of materials used, temperature and pressure. 
 Coronal tooth root design -------- reducing the shear force of the internal pump 
 Reasonable operation and operation ----- closed-loop control to provide a simple user interface 
 To extend the life of the extruder ----- reduce the strength of the extruder, such as: pressure and torque. 
 Less operating costs ---- and to provide more effective delivery approach, to avoid waste of raw materials, increase the yield of the pound extrudate. 
 PEP-II melt pump is an ideal device for the following process: 
 Film | profile | cable | Pipe | Fiber | sheet | composite extrusion | Non-woven | coating | granulation 
 Processing materials include: 
 Polypropylene hot melt adhesive fluoropolymer polysulfone, polyester | cellulose PC | the PUR | the PEEK | HIPS | ABS | of LLDPE | the PS | PA | the PVA | of PVB | the TPES of HDPE | PB | PET | the SAN | the PIB and other 
 The melt extrusion pump flow range: 0.16 | 0.3 | 0.6 | 1.2 | 1.8 | 3 | - | 10 | 20 | 40 | 100 | 175 | 300 | 750 ml | turn (standard) 
 Melt extrusion pump speed: depending on the parameters of the production process 
 Melt extrusion pump pump pressure: 690 kg wheel pressure drop of 276 kg 
 Melt extrusion pump temperature: 510 degrees 
 PEP-II, Zenith, Pumps, melt pump advantages: 
 PEP-II, polymer extrusion pump displacement design pressure in the pressure, temperature and viscosity conditions are constantly changing circumstances, to provide a stable, accurate polymer delivery. PEP-II in pressure between the extruder and die, so in the appropriate configuration of the extruder parameters can meet the more stringent tolerance requirements under the premise of a higher production capacity, to provide uniform melt material. 
 Zenith, the PEP II pump to provide a wide range of capacities and models, it can provide accurate, stable and reliable flow measurement, suitable for almost all polymers used in the plastics industry, including: chemical fiber polyester, polypropylene, nylon, acrylic fiber, fiber factors, spandex, and many of the special fiber.
