The Grundfos UP Series bronze circulator pumps are specifically designed for open loop domestic water systems. The pumps are also suitable for closed loop heating systems as well as circulation of liquid in cooling and air-conditioning systems. These pumps are generally used on open loop systems pumping domestic water. However, when water conditions exist that are not compatible with bronze then ore stainless steel pumps are recommended. Optional variable speed and mixing reset controls are available on some models to customize heat output vs. heat demand for increased comfort. Super Brute Pumps in red are 3 speed pumps all other pumps are single speed. |

Construction The UP pumps are of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. The pumps are characterized by:
Installation The pump must always be installed with horizontal motor shaft. Proper installation of the pump will have the terminal box located to one side of the pump or the other, with the conduit entry down. UP can be installed in both vertical and horizontal lines. UP pumps are intended for indoor use only.
Maximum system pressure ALL UP PUMPS: 145 PSI (10bar) Inlet pressure requirements The amount of pressure required at the inlet of a pump is a function of the temperature of the water as shown in Table 2B:

Motor UP pumps The motor is a 2 pole asynchronous squirrel-cage PSC (permanent split capacitor) motor with UL, CUL, and CSA approvals. UP pumps are available in Single-phase 115V & 230V versions with one, or three speeds. The terminal box is easily accessible and has functional cable connecting leads or terminals. Insulation class: F. The motor incorporates thermal overload or impedance protection. Therefore, no external motor protection is required.
Motor Horse powers range from 1/25 thru 1/6 and power consumption from 25 to 385 watts. Pumped liquids Depending on type, Grundfos circulator pumps are designed for the following liquids:
If the circulator pump is used for a glycol mixture with a higher viscosity than water, the hydraulic performance of the pump will be reduced. Example: 50% glycol at 68°F (20°C) means a viscosity of approx. 10 cSt and a reduction of pump performance by approx. 15%. When selecting a pump, the viscosity of the pumped liquid must be taken into consideration. |

Ambient and liquid temperatures The maximum allowable water temperature is determined by the ambient or surrounding air temperature as shown in Table 2A.
The above table refers to all standard product without timer/control options and or other special features. The ambient temperature for standard pumps with a permissible liquid temperature from +2°C to +110°C should always be lower than the liquid temperature, as otherwise condensation may form in the stator housing. Temperature requirements for pumps with timer/control and or other special features may be found on their technical data page. For all Domestic Hot water systems it is recommended to keep the operating temp. as low as possible (e.g. 140°F (60°C) to avoid calcium precipitation. |
Performance
In a pressure system, the required inlet pressure is the allowable system pressure. In a system open to the atmosphere, the required inlet pressure is the minimum distance the pump must be located below the lowest possible water level of the water source (tank, pool, etc.). |
