Product Description

GDSZ-30 series high and low temperature circulating pump belongs to high and low temperature oil bath circulation device, it can match use with 30L double-layer glass reactor. According to the specific test environment, GDSZ-30 series high and low temperature circulating pump is a new generation of products which is researched and developed on the basis of DLSB low temperature cooling liquid circulating pump and GY oil bath, with the function of one machine with multiple, and widely used in small space with a variety of specific environment. Through data programming for the equipment of intelligent temperature controller , by temperature sensing system feedback container temperature data, the controller control the compressor to make cooling, let the medium in the cold trough get low temperature; through the heater heat, so that the medium in the tough can obtain high temperature, by rapid thermal process, it can let medium temperature in the tough suiting for user needs, then through the absolutely leakage shielding circulating pump transfer the medium to an external device (such as a reactor). After the re-flux is switched, turn on the valve, the purpose of heat circulation can be achieved. When the corollary equipments(glass reactor, rotary evaporator, extraction equipment) of GDSZ-30 series high and low temperature circulating pump require rapidly warming or cooling, GDSZ pump would satisfy their requirements. It can quickly shift function between heating and cooling, and using one same medium(conduction oil), which thoroughly changed the disadvantage of conducting heating and warming in separate instruments in the past.


GDSZ-30 series high and low temperature circulating pump, its whole liquid circulation is closed, with expansion vessel, expansion tank and liquid circulation is adiabatic and does not participate in the liquid circulation, it is only the mechanical connection. No matter the liquid circulation temperature is high or low, the medium in the expansion container is lower than room temperature. The whole liquid circulation is a closed system, it can be done at low temperature without water vapor absorption, high temperature without oil mist generation.


GDSZ-30 series high and low temperature circulating pump use PID intelligent control, according to chemical process to automatic adjust power output, accuracy control the temperature of reaction process, and satisfying requirements for temperature changing.


For standard model, set max temperature difference between vessel body and clamp cover according to factory’s safety requirements, if outdoor temperature difference up to the limiting value, equipment would auto stop and give an alarm, to ensure no fracture.


For special custom-made model, we can offer max flow rate and generate min pressure and heat quantity, reach to max heat exchange rate, min systemic resistance, min pump system heat quantity and min system energy consumption.


Based on no-load lowest temperature, there are 5 models of GDSZ-30 series high and low temperature circulating pump: GDSZ-30/-20, GDSZ-30/-35, GDSZ-30/-40, GDSZ-30/-60, GDSZ-30/-80.

Product features of GDSZ-30 series high temperature circulating pump:

  1. Equip with castor, convenient to move.
  2. Light touch button is convenient to operate.
  3. Liquid discharge mouth is convenient for update medium.
  4. Inclined air inlet and outlet, round design of corner, to prevent accidental injury.
  5. Over-temperature protection and alarm system ensured safety.
  6. It can continuous cooling from 200℃ to -78℃, the cooling speed is as high as 5-10℃/m under high temperature.
  7. PID control method greatly improved the temperature control accuracy.
  8. Fully closed pipe system reduced conduction oil oxidation, and with unique oil mist cooling function. It not only lengthen oil using life but also reduce circulating pressure, increase flow rate.
