Back Vane: A radial narrow vane located on the back shroud of an impeller and … Filter Press Applications. In filter press applications, double diaphragm pumps are widely used for their ability to handle high-viscosity slurries and solids-laden fluids efficiently. Slurry Feeding: The primary role of a double diaphragm pump in a filter press system is to feed the slurry (a mixture of solids and liquids) into the filter .

Drill cuttings [1] are broken bits of solid material removed from a borehole drilled by rotary, percussion, or auger methods and brought to the surface in the drilling mud.Boreholes drilled in this way include oil or gas wells, water wells, and holes drilled for geotechnical investigations or mineral exploration. [2]The drill cuttings are commonly examined to make a record (a well log) .
Centrifugal pumps play a crucial role in various industries, including oil and gas, water treatment, and manufacturing. Understanding the terminology associated with centrifugal pumps is essential for proper operation, maintenance, and troubleshooting. In this article, we will explore centrifugal pump terminology in a PDF format, covering important aspects such as design features, efficiency factors, and technical specifications.
Centrifugal pumps can handle a maximum viscosity similar to 30 weight oil at room temperature. Above this viscosity a positive displacement pump should be used Volute / Casing Housing
Design Features
One key design feature of a centrifugal pump is the incorporation of two cut waters to prevent shaft deflection when the pump is operating off of the Best Efficiency Point (B.E.P.). This design element helps maintain the alignment of the pump shaft and impeller, ensuring smooth operation and minimizing wear and tear on critical components. However, it is important to note that having two cut waters can lower the efficiency of the pump, especially when operating at non-optimal conditions.
Efficiency Factors
Efficiency is a critical performance parameter for centrifugal pumps, as it directly impacts energy consumption and operating costs. When a centrifugal pump operates away from its B.E.P., efficiency can decrease due to factors such as increased internal recirculation, higher hydraulic losses, and reduced impeller effectiveness. It is essential for pump operators to monitor efficiency levels and make adjustments to ensure optimal performance and energy savings.
Technical Specifications
Centrifugal pump technical specifications are outlined in detailed catalogues and manuals provided by manufacturers. These documents contain information on pump size, flow rates, head capacities, materials of construction, and operating conditions. Engineers and maintenance personnel rely on these specifications to select the right pump for a specific application, install it correctly, and troubleshoot any issues that may arise during operation.
