DLSB series low temperature coolant circulation pump is a low temperature constant temperature liquid circulation equipment produced by our company based on the research and production of China's laboratory, pharmaceutical, chemical and other industries, and actively absorbs the advanced technology of Germany and Japan; Constant temperature liquid bath, low temperature constant temperature condensation cooling, low temperature constant temperature storage, establishment of the second low temperature constant temperature field, etc., is an indispensable instrument for medicine, chemical industry and scientific research experiments.
Features:
1. Air-cooled (imported) fully enclosed compressor unit with reliable quality;
2. Refrigeration unit special relays, protectors, capacitors, etc. are high quality devices, quality assurance;
3. Digital display temperature control, easy to operate, eye-catching;
4. Can be matched with a variety of instruments (rotary evaporator, fermenter, chemical reactor, freeze drying equipment, biopharmaceutical reactor, etc.);
5. Large cooling capacity and fast cooling speed greatly improve work efficiency;
6. It can effectively protect all kinds of precision equipment and instruments under normal conditions of water shortage, water quality, water pressure, poor water temperature and high temperature working conditions;
7. The flow rate of the circulating pump of the machine can be adjusted or customized, which greatly meets the actual needs of different users;
8. All models of this machine can be reasonably matched between low temperature and cooling capacity, low temperature and container volume according to user requirements.
Peristaltic pump
There are a few plaster sprayers that have a peristaltic pump (a tube squeezed by rollers) which also requires compressed air to produce a spray. These types of plaster sprayer can also spray textured coatings with particle sizes up to about 3mm diameter, providing that they are not solvent based.
Piston pump
Newer types of plaster sprayer have a piston pump, which has sufficient pressure to spray smooth (untextured) plaster without compressed air. Full airless pumps are sometimes used to spray smooth plaster, although they are not ideal as the flow rate is too low for volume projects; however, they can be used to spray solvent-based plasters.
Air operated piston type supply pumps can put out as much as 27 gpm. Like the Graco Bulldog 10:1 at about 9 gpm and the Lincoln Pile driver 5:1 at about 27 gpm. These flow-rates are calculated at a maximum of 120 cfm air supply. Material supply hoses are medium pressure at about 600 psi. These pumps are material supply pumps only and additional air is required at the Spray Gun to propel the material to the surface. These guns are usually an internal mixture type guns where the material and air exits the gun together.
