√The power supply is a 90V~240V wide voltage input switching power supply, which supplies power to the cooling system, stepper motor driver, control system and other devices.
√The control system is the core part of the CX-HL series of high-pressure infusion pumps. It allows users to set the flow rate according to their needs, select the working mode of the pump, write time programs and GLP event records, etc.
√The pressure measurement system can measure the size of the liquid pressure in the liquid path, and the user can select different chromatographic columns and mobile phases according to this value; by setting the maximum pressure and minimum pressure, the high-pressure infusion pump can be in the best working state and avoid Occurrence of overpressure and leakage.
√The stepper motor driver and stepper motor are high-voltage power devices, which ensure that the liquid in the liquid path can smoothly flow through the chromatographic column and the flow cell, so that the infusion work can proceed smoothly.
√The pump housing unit part mainly includes pump head assembly, one-way valve assembly, cam mechanism and so on.
According to different infusion volume, CX-HL series infusion pump can be divided into the following seven types:

Pump Head	Flow rate range	Maximum working pressure	Material

FAQ

Q1.What is a constant flow pump?

A constant flow pump is a type of pump that can maintain a stable flow rate when external conditions change. It is commonly used in situations where liquid flow is precisely controlled, such as in laboratories, industrial production, and medical equipment. The working principle of a constant flow pump is to ensure that the output flow remains constant by adjusting the speed or flow control device of the pump, avoiding flow fluctuations caused by changes in pressure, temperature, or pipeline resistance.
Common types of constant flow pumps include:
Peristaltic pump: It pushes liquid flow through a compressed hose, with stable flow rate and suitable for conveying volatile or particle containing liquids.
Gear pump: uses the meshing rotation of two gears to transport liquids, suitable for high-precision transportation.
Diaphragm pump: It drives fluid through reciprocating diaphragm motion and is widely used in the chemical and water treatment industries.
Piston pump: It pushes fluid through the reciprocating motion of the plunger, suitable for fluid transportation under high pressure conditions.
Constant flow pumps have the characteristics of precise control, durability, and strong adaptability, and are widely used in situations where stable flow is required.

Agriculture:
In agriculture, constant flow pumps are used to precisely control the injection of fertilizers or pesticides, especially in drip or micro irrigation systems, to improve resource utilization and promote crop growth through a constant flow rate.
Constant flow pumps are suitable for various fields that require precise liquid transportation due to their high precision, stability, and controllability.

Q3.Working principle of constant flow pump?

The working principle of a constant flow pump is to maintain a constant liquid or gas flow rate by controlling the pump's speed, pressure, or fluid path. Even in the event of changes in external conditions such as pressure, viscosity, pipeline resistance, etc., the pump can still stably transport the medium.
The working principle of different types of constant flow pumps may vary, but their core goal is to achieve a constant flow rate.
The working principle of a plunger constant flow pump is that the plunger pump changes the pump chamber volume through the reciprocating motion of the plunger, and sucks in and discharges liquid. The volume change of the pump chamber is directly related to the movement speed and frequency of the plunger, so by controlling the plunger movement, the liquid flow rate can be adjusted and a constant output can be maintained.
Characteristics: Commonly used in high-pressure systems, with high flow accuracy but significant flow pulsation.
