A pump is useful for lautering and transfers to the fermenter. Use only food-safe pumps rated up to 100°C.

The small Rotekt 12V pumps are commonly used in homebrewing setups:

Camlock fittings from [Braubebo](https://www.braubebo.de/camlock/) are also a solid option.

### SSR (solid state relay)

Brautomat can switch SSRs directly. SSRs switch a 230V AC load using a 3-5V DC control signal from Brautomat.

Typical SSR use cases:

* switch a socket for an agitator power supply
* switch a NACHGUSS/sparge-water heater
* switch a ring heater
* switch a pump power supply

### Relay modules

Not every load needs a high-power SSR. Agitators and pumps are often fine with low-cost relay boards.

### Ring heating elements

A ring heater can help during boil if IDS power is not enough for a strong rolling boil.
