The unit consists of a Grundfos CMB CMB-SP 5-28 cast iron pump and a Grundfos PM2 pressure manager that allows the pump to start and stop automatically according to demand.

Recommendation:  A pressure tank extends pump life, stores energy, reduces noise, reduces pump starts and protects against heat expansion, see drop-down menu.
