The Birchmeier Pomp Zonder Zuiger Nr. 12 is a high-quality pistonless pump designed for professional and industrial applications requiring reliable fluid transfer. This pump model features a robust construction with corrosion-resistant materials, ensuring long-term durability in demanding environments. With a maximum working pressure of 10 bar and a flow capacity of 60 liters per minute, it efficiently handles various liquids including water, chemicals, and light oils. The pump body measures 32 cm in height, 18 cm in width, and 15 cm in depth, with a total weight of 2.8 kg for manageable portability. It operates effectively within a temperature range of -10 °C to 80 °C, making it suitable for diverse climate conditions. The pistonless design reduces maintenance requirements and minimizes wear on internal components, providing consistent performance over extended periods. Connection ports are standardized at 1/2 inch (12.7 mm) for compatibility with common industrial hose fittings. This pump is engineered for continuous operation with minimal vibration and noise levels below 65 dB during normal use. The external housing features a textured grip surface for secure handling, even when wearing protective gloves. All seals and gaskets are manufactured from chemical-resistant materials to prevent degradation when transferring aggressive liquids. The pump requires minimal setup and can be mounted in multiple orientations to accommodate various installation configurations. It is particularly well-suited for agricultural spraying systems, industrial cleaning applications, and fluid transfer operations where reliability and consistent flow rates are essential. The motor housing includes integrated thermal protection to prevent overheating during prolonged use. This model represents an evolution from previous Birchmeier pump designs, incorporating improved efficiency and enhanced material durability based on user feedback from professional applications.
