The question of how to select a pump in an injection molding application is crucial for successful results. The right pump increases the efficiency of the injection process and reduces operating costs. There are many criteria to consider when selecting a pump, and when these criteria are properly evaluated, a long-lasting and reliable system can be established. Furthermore, compatibility with the properties of the injection material is crucial in pump selection.

Pump Capacity and Pressure Requirements

Pump capacity is the most critical factor in grouting. The pump must be suitable for the volume of the material being injected. Insufficient capacity will cause process disruptions. Furthermore, the pump must be able to provide the required pressure. Pressure values vary depending on the viscosity of the grout and the application area. Therefore, pressure requirements must be calculated in advance.

Comparison of Pump Types

Piston, diaphragm, and gear pumps are generally preferred for injection applications. Piston pumps offer the advantages of high pressure and precise dosing. Diaphragm pumps, on the other hand, are more durable in abrasive materials but have lower pressure capacity. Gear pumps, on the other hand, provide continuous flow and are used in low-pressure applications. Therefore, the pump type selection varies depending on the type of injection.

Material Compatibility and Pump Material

Material compatibility should be considered when selecting a pump. Chemicals used during injection must not react with the pump material. The pump's material durability is particularly important when using acidic or basic materials. Stainless steel and special coatings are frequently preferred for longevity.

Energy Efficiency and Ease of Maintenance

Pump energy consumption affects the total cost of the injection application. Highly energy-efficient pumps offer long-term advantages. Ease of maintenance is also a selection criterion. Easy pump disassembly and assembly and spare parts availability ensure uninterrupted operation. Therefore, the service support network should also be considered when selecting a pump.

Technological Features in Pump Selection

In recent years, pumps used in injection applications have been equipped with digital control and automation systems. These technological features allow for precise dosing. Furthermore, pump performance can be continuously monitored, minimizing the risk of malfunction. Automation systems save time by optimizing injection processes.
