Interesting facts about the pump and filter technology
Activated carbon is pure and higly porous carbon with a large surface area (of up to 300 m² per gram). It is typically used as an adsorbent.
Constant forward and backward movement of objects by means of a connecting rod. The driving movement is carried out by a motor with extra-low voltage (24 V) for protection; with infinitely variable speed regulation on request.
Bag filter are surface filter. The advantage is, that the filter cake can not fall back to the bath. However they have to be exchanged quite often.
Bypass line
The center shaft support the inner magnet.
Pumps and filters made by RENNER are designed and manufactured to be used in several chemical processes. Depending on the fluid made of different materials.
Centrifugal pumps have suction side and pressure side connections.
Copolymer is a polymer which is composed of several different monomer.
Cos phi = power factor
DC current = direct current
DC voltage = direct current voltage
For the removal of organic and inorganic impurities from aggressive and neutral liquids and gases by means of deep-bed and surface filtration.
Electronic monitoring of motor currents protects the pump from dry running, overheating and overload.
If the above mentioned operating states are not absolutely impossible with your installation, you should use an electronic process monitor to switch off the pump before it is damaged. Such monitors will not only avoid damage to the pump, but also downtime and costs resulting thereof. At the same time, the monitor checks the pumping process for the set delivery rate. Once the cause of a malfunction is eliminated, the pump is immediately ready to continue operation. The process monitor is easy to install into the pump’s power supply unit. As it is not necessary to build it into pipe runs, this process monitor also is ideal to retrofit existing installations. Four different types of process monitors are available.
Duty type S1 to S12
Ethylenchlortrifluorethylene (ECTFE) is a thermoplastic Copolymer out of Ethylen and Chlortrifluorethylene.
RENNER pumps with a high efficiency.
Electronically commutated. Brushless.
Surface treatment
With a variable speed motor for centrifugal pumps you can safe power consumption.
Ethylene-Propylene-Diene-Rubber (EPDM) is an Ethylene- and Propylene-Monomer made of Elastomer. Which is principally used as a sealing material.
For the removal of organic and inorganic impurities from aggressive and neutral liquids and gases by means of deep-bed and surface filtration.
Filter bag is a surface filter.
This filter element is a surface filter.
Filter housings for surface and deep bed filtration.
A filter screen is a filter element.
Procedural system to separate solids from the fluid.
All metal parts of a RENNER pump are protected with a special protective coating. Special colour is no problem.
Fluororubber (FKM) is a sealing material.
Flange connections.
The liquid level on the suction side has to be higher than the suction port of the pump.
Flow rate of a pump.
Liquid
Variable speed drive allows an adjustment of centrifugal pumps according to the individual application. At the same time the power consumption will be minimised.
Number of oscillation per second. Unit Hertz [Hz].
The vanadium redox battery exploits the ability of vanadium to exist in solution in four different oxidation states, and uses this property to make a battery that has just one electroactive element instead of two.
The main advantages of the vanadium redox battery are that it can offer almost unlimited capacity simply by using larger and larger storage tanks, it can be left completely discharged for long periods with no ill effects, it can be recharged simply by replacing the electrolyte if no power source is available to charge it, and if the electrolytes are accidentally mixed the battery suffers no permanent damage.
The main disadvantages with vanadium redox technology are a relatively poor energy-to-volume ratio, and the system complexity in comparison with standard storage batteries.
