Low-flow, high-head solid-liquid transfer pump
Thread Content
Flow rate: 10–50 L/H, head: 350 m, solid content: 10%； No corrosion at room temperature. What type of pump is used for transportation? Does that one have it? Please give some advice, expert: dizzy:
About 5 years ago, I installed several slurry feed pumps with a capacity of 20 L/H and a pressure of over 200 bar; the solid content was around 50%. Plunger metering pumps were used, and they performed very well. At that time, a rather special pump chamber design was used for slurry, but your operating conditions are far less demanding than those associated with slurry; perhaps an ordinary plunger metering pump will suffice if a wear-resistant packing and plunger are used.
If the flow rate is too low, diaphragm pumps with a metering type can be considered
