On October 19, 2011, discussions regarding the concept of negative suction pressure in centrifugal pumps began to gain traction within the industry. It was observed that a pump could potentially experience negative suction pressure under certain conditions, leading to a range of implications and considerations for engineers and operators.

Typically, in a horizontal pump, this is measured from the center of the suction pipe at the pump to the top of the sump level. Since centrifugal pumps don't normally have suction lift capacity, there must be positive pressure at the impeller eye.

Negative Suction Centrifugal Pump

In the realm of fluid dynamics and pump operation, negative suction pressure in a centrifugal pump refers to a scenario where the pressure at the pump's inlet falls below atmospheric pressure. This situation can occur due to various factors such as high elevation differences, vaporization of the pumped fluid, or inadequate priming of the pump.

Positive and Negative Suction Pump

Centrifugal pumps can operate under both positive and negative suction conditions, with positive suction pressure being the typical scenario where the pressure at the pump inlet exceeds atmospheric pressure. However, negative suction pressure poses challenges in terms of pump performance, efficiency, and potential cavitation risks.

Maximum Suction Pressure of Pump

Understanding the maximum suction pressure capabilities of a pump is crucial for ensuring optimal performance and preventing issues such as cavitation. Engineers must consider factors such as pump design, fluid properties, system layout, and operating conditions to determine the safe operating range for suction pressure.

Calculating NPSHA for Pump

The Net Positive Suction Head Available (NPSHA) is a critical parameter in evaluating the suction performance of a pump. It takes into account the pressure head at the pump inlet, atmospheric pressure, and the vapor pressure of the pumped fluid to assess the likelihood of cavitation occurring in the system.

Negative Suction Head Pump Example

To illustrate the impact of negative suction pressure on pump operation, consider a scenario where a centrifugal pump is located at a higher elevation than the fluid source. In this case, the pump may experience negative suction head, leading to reduced efficiency, potential cavitation, and operational challenges.

Suction Pressure Calculation for Pump

Calculating the suction pressure for a pump involves analyzing the system's hydraulic characteristics, including pipe losses, elevation changes, fluid properties, and pump performance curves. Engineers use sophisticated calculations and modeling techniques to determine the optimal suction pressure for efficient pump operation.

Pump Suction Pressure vs Discharge

The relationship between pump suction pressure and discharge pressure is crucial in maintaining the pump's performance and preventing issues like cavitation or pump overload. Properly balancing these pressures ensures smooth operation, optimal efficiency, and extended equipment lifespan.

SJ-M/M shaker screens have steel and PT frame types for your choice. Both of them are ideally as the replacement screens of SWACO MONGOOSE PRO and MEERKAT PT shale shakers. MONGOOSE units have 4 pre-tensioned screens per shaker basket and the MEERKAT units have 3 pre-tensioned screens per shaker basket. The mesh types are XR, XL, HC, MG available.The primary function of a shale shaker is to remove drilled solids, cuttings, and debris from the drilling fluid, also known as mud. Shale shakers utilize vibrating screens with varying mesh sizes to separate solids of different sizes from the .
