Filter press, negative pressure centrifugal pump

Filter press, negative pressure centrifugal pumpThe actual working point of the pump is determined by the intersection of the pump's curve and the pump's device characteristic curve. The selection and use of pumps should ensure that the working point of the pump falls within the working range to ensure operational economy and safety. In addition, when the same pump transports liquids with different viscosities, its characteristic curve will also change. Usually, the characteristic curve provided by pump manufacturers refers to the characteristic curve when delivering clean cold water. For power pumps, as the viscosity of the liquid increases, the head and efficiency decrease, and the shaft power increases. Therefore, in industry, liquids with high viscosity are sometimes heated to reduce viscosity and improve conveying efficiency.

Filter press, negative pressure centrifugal pumpfeature

When the filter chamber of the filter press is filled with slurry, the pump should continuously provide high pressure to the filter chamber to ensure that the moisture in the slurry is quickly squeezed out. The pump seal is often prone to failure under the combined effects of high pressure, high concentration slurry, temperature, and corrosion, resulting in the entire filtration system being unable to produce normally.

problems solved

What structure does the filter press pump adopt to solve these problems.

(1) Adopting a double bladed wheel structure, its performance curve is steep, which not only solves the problem of running without overload but also solves the problem of pump stagnation, and can achieve low speed and high pressure, reducing the wear of the water pump.

(2) The use of impeller reverse installation and negative pressure sealing structure has solved the leakage problem.

This filter press pump is a low-speed large channel pump designed for transporting slurry containing large particles or slurry containing sand and gravel. Its structure adopts an axial inlet and a radial outlet to ensure that larger sand and gravel particles are immediately thrown out through an open impeller after entering the pump chamber.
