It is designed to control and measure the volume of liquid that passes through the anything at any given point in time. A dosing pump usually moves an exact amount of liquid at a set time interval, offering an exact, measurable volumetric flow. This is particularly important in juice production where a high degree of control is required to ensure consistent quality and output of high sugar content.
In addition to the ability to precisely monitor the levels of sugar contained within a particular can (a critical step in the production process), the accuracy of the dosing pumps is also affected by various other factors. These may include ambient temperature, humidity, wind, level of precipitation and human intervention.
Dosing pumps are designed to work in extreme environments, but they are subject to various influences that diminish their performance over time. The dosing pump must perform well under these conditions and ensure robust performance over extended periods. Some of these include high temperatures, excessive rainfall, extremely low temperatures and dry dust conditions.
The main component of a dosing pump is its suction pipe and a heat pump. The primary function of this pipe is to regulate the amount of liquid which moves into the can from a lower region or outside the plant. Suction pressure is usually measured via a digital gauge scale. This gauge usually indicates the pressure in a certain area or by a specific reference. The reason for using these gauges is to provide a reliable indication as to the suction pressure applied to the pump.
Although the dosing pump performs a vital role within the manufacturing process, it must also be able to withstand extreme physical conditions. This is usually done by using a stainless-steel pipe. This helps prevent corrosion of the pipe, which could lead to pump failure and reduced efficiency.
A stainless-steel pipe is the ideal material because it is capable of resisting corrosion and rusting. The pump is usually placed directly onto the pipe and left in place until needed. If the pipe should corrode or rust, the entire pump may need to be replaced.
However, some manufacturers prefer to leave the pipe in place during normal operation in order to maintain efficiency. When using a noncorrosive dosing pump, it is recommended that a similar pipe is used in the adjacent tank in case of a problem with one of the tanks.
