2026-07-04 Application of Melting Gear Pumps in Plastic Pelletizing
Melt gear pump is the core supporting equipment of plastic granulation production line, usually connected to the granulation process in the configuration of extruder+melt gear pump+die head, suitable for granulation processing scenarios of most thermoplastic plastics such as PS, PP, PET, PVC, PC, etc. 1、 Core application value Stabilize voltage and flow to ensure granulation quality It controls the outlet pressure fluctuation of the granulation system within 0.5% through the forced conveying effect of gear meshing, and the flow accuracy can reach 0.5-1%, completely eliminating the problem of
2026-07-02 Three core dimensions for selecting melt booster pumps
The melt booster pump is a core conveying equipment in processes such as polymer material extrusion, granulation, and film production. Its selection accuracy directly determines the operational stability of the production line, the precision of product molding, and the service life of the equipment. Unlike the benchmarking selection of general machinery equipment based on parameters, the scientific selection of melt booster pumps requires abandoning the extensive mode of single parameter matching. Instead, it should be based on three core dimensions: material characteristics, process condition

2026-06-23 Four Major Causes of Melt Gear Pump Seizure in 90% of Cases
Melt gear pump seizure is a common failure in high-viscosity polymer processing operations. A comprehensive, professional analysis must be conducted, taking into account equipment design, material properties, and operating procedures. The core causes can be categorized into four major types: First, mismatched preheating conditions. If the system is not fully preheated throughout the entire system as required by the process before startup, the high-viscosity melt remaining in the pump chamber will not be completely melted. The overall viscosity will far exceed the startup threshold, causing a s

2026-06-17 How Do Batte Melt Pumps Optimize Extrusion Lines?
Based on feedback from the actual operation of extrusion lines, installing a melt pump in an existing extrusion system can bring about systematic improvements across multiple dimensionsincluding product quality, raw material consumption, and line operation and maintenancemaking it a core upgrade for enhancing extrusion production efficiency and quality. The most tangible value of a melt pump lies in its dual optimization of product quality and raw material costs: the dimensional stability of extruded products depends entirely on the precision of melt output. The smaller the fluctuations in pre
2026-06-13 Three Types of Gears for High-Temperature Melt Pumps
The gears commonly used in high-temperature melt pumps can be classified into three types based on tooth direction: straight-tooth, helical-tooth, and herringbone-tooth. Among these, external-meshing involute profiles are the most widely used, as they are suitable for harsh operating conditions involving high temperatures (up to 350C), high pressure, and high viscosity. The following describes the characteristics of these three types of gears: I. Straight-Tooth Gears (Economy Type) In straight-tooth gears, the tooth direction is parallel to the axis. They are the simplest in structure and have
2026-06-10 What are the key features of melt pumps for rubber hose extruders?
The core features of melt pumps for rubber hose extruders (rubber melt pumps) are precise pressure control and stable delivery. They effectively address the processing challenges posed by the high viscosity and tendency of rubber melt to stick to the walls, while ensuring dimensional accuracy and continuous production of rubber hoses. 1. Structural Design Adapted to Rubber Processing Characteristics High-viscosity and high-temperature resistance: The pump body is made of wear-resistant alloy, and the inner walls are treated with a special coating. This allows it to withstand the temperatures c
2026-06-01 The Core Logic Behind Melt Pumps in Resolving Extruder Pressure Fluctuations
The Zhengzhou Batte Melt Pump is a core component for addressing pressure fluctuations in extrusion lines. It relies on the positive displacement principle to achieve precise and stable pressure control: a pair of precision-meshed gears inside the pump ensures a fixed volume of extruded melt with each rotation. By locking the rotational speed, a constant flow rate is maintained, unaffected by downstream resistance, thereby stabilizing pressure at its source. Once installed, production line pressure fluctuations can be controlled within 0.5%, with pressure stabilization accuracy more than ten t
