Product Overview
The Grundfos CMBE TWIN 3-93 is a variable speed pressure boosting pump system designed for domestic and light commercial applications including pressure boosting, irrigation, and system pressurisation. The twin configuration consists of two pumps operating in parallel, ensuring higher capacity and stable pressure under varying demand conditions.
Constructed with stainless steel pump housing and multistage stainless steel impellers (AISI 304), the system provides excellent corrosion resistance and durability. The booster system includes dual pumps, expansion tanks, pressure sensors, pressure gauges, and a base frame, enabling efficient multi-pump operation with automatic cascade control.
The system operates at a rated flow of 4.2 m³/h with a corresponding head of 66.3 metres. Based on the performance curve, it achieves a maximum head of approximately 100 metres at low flow conditions. The system automatically adjusts performance by switching pumps on or off and varying speed based on demand.
The unit is powered by two electric motors rated at 1.5 kW (P2) each, operating on a 1 x 200–240 V, 50 Hz supply. Integrated speed control ensures efficient operation and consistent pressure delivery.
