Our competitive advantage

Pumps from Thomas have been used in the transportation, compression and evacuation of gases for more than 65 years. From the outset Thomas has also been highly involved in the development and manufacture of special pumps for aeration of lead-acid batteries. Electrolyte circulation systems have been optimized in cooperation with battery manufacturers and the manufacturers of charging stations and are successfully used throughout industry.

Function

When batteries (rechargeable lead-acid batteries) are charged, the battery acid is layered in the individual cells as a result of the differences in density. This reduces the useful power of the battery. Conventional charging processes produce strong gassing through defined overcharging when fully charged. This gassing process mixes and homogenizes the electrolyte. At the same time, however, this also means a longer charging time and an increase in temperature. The energy consumption rises in consequence and the higher temperature also leads to higher water consumption. Electrolyte circulation ensures that the electrolyte is gently mixed by an air stream. Ambient air is pumped into the battery through a small tube reaching down to the bottom of the battery. The pumped output is produced by a fixed-displacement electric diaphragm pump and delivered to the tubes in the respective cells via hoses.
