WMD15 Low-pulsation Pump Head

The WMD15 series low-pulsation pump head offers a flow rate range of 0.006–1740 mL/min and is compatible with tubing sizes 13#, 14#, 16#, 17#, 19#, and 25#. Featuring proprietary low-pulsation technology, it enables smoother fluid transfer with reduced pulsation and improved flow continuity, making it especially suitable for high-stability applications such as dispensing, coating, and chemical synthesis. Constructed from aluminum alloy and SS304 stainless steel, the pump head is robust and durable, supporting reliable long-term continuous operation at high speeds. Application fields: laboratories, new energy, environmental protection, and chemical industries. Typical applications: online COD water quality analyzers, automatic titrators, and form-fill-seal machines.
