What is a vertical pump? Vertical pumps are also called vertical turbine pumps, which are partially submerged in liquid when working. It has the characteristics of a small footprint, reliable use, convenient maintenance, strong corrosion resistance, and no mechanical seal leakage. Products are widely used in high-rise water supply, chemical acid-base transmission, PCB pickling, swimming pool equipment and other industrial applications.

In industrial applications, a pump is a mechanical product that is widely used. Pump types can be roughly divided into horizontal pumps and vertical pumps.Vertical pumps can be divided into submersible pumps, vertical centrifugal pumps, vertical turbopumps, vertical single-stage impeller pumps, and other vertical pump types.

The application of the pump has a wide range. If it is distinguished by size, the large industrial pump can transmit tens of thousands of cubic meters of liquid per hour, while the smallest pump can control the flow rate to 1% ml per minute.Many types of liquids are transported by pumps, including water (pure water, tepid water), medicinal liquids, acidic liquids, alkaline liquids, etc.

What should be paid attention to in the selection of chemical pumps
Based on mastering the basic data of pump selection, what should be paid attention to in the selection of chemical pumps:
(1) The process flow where the pump is located. The basic parameters such as the flow rate and head of the pump should be reasonably determined according to the needs of the process. Generally, the normal wear of the pump and the change of the rotational speed may cause the head to drop. Therefore, the head of the pump can have a margin of 2% to 5% when selecting a pump. But the maximum cannot exceed 10%. The basic principle is to ensure that the pump operates within the efficient range. In addition, the information of the pump inlet status can be obtained through the process, which can be used for calculating the NPSH of the device.
6 Reasons Why Acid-resistant Pump Mechanical Seal Fail？

6 Reasons Why Acid-resistant Pump Mechanical Seal Fail？

Feb 25, 2022

02-252022

Sudden leakage Due to the following reasons, chemical acid-resistant pump seals will have sudden leakage.
    1. The acid-resistant pump vibrates strongly and evacuation destroys the friction pair.
    2. Acid-resistant spring breaks.
    3. The acid-resistant anti-rotation pin falls off or the transmission pin is broken and loses its function.
    4. The failure of the acid-resistant circulation protection system causes the dynamic and static rings to undergo sudden changes in cold and heat, resulting in deformation of the sealing surface or cracks.
    5. Due to the temperature change, the medium around the friction pair condenses and crystallizes, which affects the acid-resistant seal.
How to Calculate the Efficiency of Chemical Resistant Pumps？

How to Calculate the Efficiency of Chemical Resistant Pumps？

Feb 23, 2022

02-232022

The efficiency of the chemical resistant pump refers to the ratio of the effective power of the acid and alkali resistant pump to the shaft power. η=Pe/p The power of the chemical resistant pump usually refers to the input power, that is, the power transmitted by the prime mover to the pump shaft, so it is also called the shaft power, which is represented by P. The effective power is the product of the lift of the chemical resistant pump, the mass flow rate and the acceleration of gravity. Pe=ρg QH (W) or Pe=γQH/1000 (KW) ρ: Density of pumped liquid (kg/m3)
