When comparing pump specifications, many buyers focus only on maximum flow rate. However, for positive displacement pumps, there is a much more fundamental parameter: Displacement per Revolution (often called displacement volume).Whether you...


When sourcing pumps, Maximum Discharge Pressure (or Maximum Outlet Pressure) is a critical parameter. Positive displacement pumps will keep pushing fluid against resistance until something breaks...

When designing a production line or replacing an old unit, one of the most critical decisions is choosing the right pump port connections. The inlet and outlet sizes of your pump directly affect your flow rate, system pressure, and the overall lifespan of your equipment. If your ports are too small, your pump will starve. If the connection type is wrong, you risk leaks, fluid contamination, or costly downtime. As a dedicated manufacturer of industrial and hygienic pumping solutions, we created this port selection guide to help you understand how inlet and outlet sizes work across internal gear pumps, sanitary twin-screw pumps, and lobe rotor pumps...

When reading a pump specification sheet, the first number most buyers look at is the flow rate. It tells you how much liquid the pump can move. However, you will often see this listed as the Nominal Flow Rate (sometimes called Rated Flow Rate). But what does "nominal" actua...

Maximum speed is the highest speed a pump can safely run, measured in RPM. It determines pump wear, fluid damage risk, and efficiency. Internal gear pumps typically run at 500–1,500 RPM for thick fluids, while sanitary twin-screw pumps reach 3,000–3,600 RPM, offering dual-duty transfe...

When purchasing a sanitary rotary lobe pump, the most common question buyers ask is: 'My factory requires a specific hourly capacity, so which frame size (model) should I choose?' A rotary lobe pump is a positive displacement pump. Its flow rate is tightly connected to the frame size, displacement per revolution, and operating speed. Below is a professional sizing guide to help...
