Bosch Pump Stations

T The Bosch KS pump station is designed for one solar storage tank. For two tanks, two solar stations can be combined in one system. This arrangement provides two separate return connections with separate pumps and flow limiters. This enables the hydraulic balancing of two storage tanks with different pressure drop values. Another application of two pump stations in one system is the implementation of a solar system with two collector arrays in different orientation (east/west control). Here too it is important to have two separate return connections with separate pumps and flow limiters.

  • Easy to install with pre-assembled, fully integrated 2-line pump kit
  • Modules connect to solar pump station to provide common solar hydraulic options
  • Quiet, variable flow circulation solar system pump
  • Line connections with compression fittings
  • Integrated fill and drain valves for easy service and maintenance
  • Up 10% higher solar gain thru heating control integration using the TR0301U
  • Diverse performance levels depending on the size of the collector field

The KS line of Solar Pump Stations serve as the circulation system for transferring the heat transfer fluid from the collectors to the storage tank, working in conjunction with the control to maintain consistent high-efficiency.


TR0301 Control Station station transfers the heat from your collectors to your tank, maintaining a constantly high efficiency. The combination of a solar controller with a boiler control unit offers you even more possibilities. The automatic reduction of heat temperature can reduce burner starts by up to 24%, saving up to 10% fuel during domestic hot water heating.

TR0603mcU is a sophisticated controller that allows controlling of a large variety of different systems from simple DHW only systems to systems with multiple tanks, DHW, space heating support, and pool heating.
