Grundfos ALPHA1 32-60 180 Circulator Pump (93074162) | Termix.ro
Description
Grundfos ALPHA1 32-60 180 Circulation Pump (PN: 93074162)
The Grundfos ALPHA1 32-60 180 circulation pump (Part Number 93074162) is a high-efficiency canned-rotor circulator designed for moving liquids in domestic and commercial heating and cooling systems. Built around an electronically commutated permanent-magnet motor (ECM technology), the ALPHA1 delivers exceptional energy performance with a variable power consumption ranging between just 4 W and 45 W, achieving an Energy Efficiency Index (EEI) of ≤ 0.20.
Featuring a 2" (DN32) threaded connection and a 180 mm port-to-port dimension, this model is an ideal choice for both new installations and direct replacements in radiator systems, underfloor heating, or boiler loops.
Key Features & Benefits:
-
3 Pre-Set Control Modes: Proportional pressure, constant pressure, and constant curve (3 fixed speed levels), easily selectable via a single control button.
-
Low Power Consumption: Intelligent motor control adjusts performance based on actual system demand, significantly reducing electricity bills.
-
High Starting Torque: Eliminates the risk of rotor lock/seizure after long idle periods (such as during summer months).
-
Robust Construction: Electrocoated cast iron pump housing for enhanced corrosion resistance, featuring ceramic shaft and bearings for smooth, quiet operation.
-
Easy Electrical Connection: Fast wiring with the tool-free ALPHA Plug connector.

Frequently Asked Questions (FAQ)
Q: What do the numbers "32-60 180" stand for in the model name?
-
32: Refers to the nominal connection diameter (DN32 / 2" thread size).
-
60: Represents the maximum pump head of 6.0 meters.
-
180: Indicates the overall fitting length / port-to-port distance (180 mm).
Q: Are pipe unions included with the pump?
-
The package typically includes the sealing gaskets and the ALPHA Plug electrical connector. The set of 2" x 1 1/4" pipe unions is usually sold separately if not already present on your installation.
Q: Can this pump be used for domestic hot water (DHW)?
-
For potable domestic hot water loops, pump housings made of bronze or stainless steel (such as the Grundfos COMFORT or ALPHA N ranges) are required. The cast iron housing of the standard ALPHA1 is designed for closed heating and cooling circuits.
