Centrifugal and Positive Displacement Pumps

When it comes to pumping liquids, there are two main types of pumps: positive displacement pumps and centrifugal pumps. Positive displacement pumps work by trapping a fixed amount of fluid in a cavity and then pushing it out into the discharge pipe. On the other hand, centrifugal pumps use a spinning impeller to transfer the kinetic energy from the motor to the liquid, which increases its velocity and moves it through the discharge point. While both types of pumps have their own advantages and disadvantages, it's important to choose the right one for the job based on factors such as flow rate, pressure, and viscosity of the fluid being pumped.

One of the primary reasons for selecting positive displacement pumps is their capability to handle high viscosity fluids at high pressures and low flows effectively. Unlike centrifugal pumps, positive displacement pumps do not experience a decrease in efficiency due to pressure. Centrifugal pumps are commonly used due to their simplicity, but when faced with challenging conditions where centrifugal pumps may fail, positive displacement pumps provide a reliable solution. The ability of positive displacement pumps to operate at any point on their curve ensures their suitability for handling difficult conditions.

Positive displacement pumps can be classified into two categories: rotary and reciprocating. Despite their common working principle, each type of pump has distinct design features and advantages. These categories enable the selection of pumps based on specific requirements, ensuring maximum efficiency and performance.

Packing, Storage, Handling and Transportation

The plywood cases will contain a single set of pump, along with fixed timbers and a protective plastic film inside for packaging.

We will have an inspection at our factory to ensure that the containers are packed correctly and without any damage. The purpose of this inspection is to witness the container loading process and make sure that the packaging is done in a proper manner. It is important for us to prevent any potential damage to the goods during transit. Therefore, we will closely monitor the packing process to guarantee that all items are securely packaged and loaded into the containers. By doing so, we can ensure that the products reach their destination intact and in good condition.
