The NELSON waterer series 300 is an electrical heated, thermostat controlled and frost proof self filling water trough.
The operation of the self-sucking membrane pasture pump is instinctively familiar to animals. The thermo spring is equipped with particularly smooth running membrane pump (0,6l/stroke). It is a good value for money pump at all locations without water and electrical supply for all year round use. Water can be taken out of a stream or pasture well. The thermo spring has to be mounted on a roughly 1 m² concrete base directly above the pasture well. The housing insulates the sucking hose. The natural earth heat keeps the pump frost free down to -5 ºC. The supplied oil heating has to be turned on in colder days. It prevents freezing of the pump down to -25 ºC, depending on the wind force at the location.
