NCE PS

Product catalog summary

Construction: The energy-saving circulating pump is designed for sanitary hot water systems and features a variable speed synchronous motor with a permanent magnet, controlled by an onboard inverter. The pump casing is made of bronze.

Applications: Suitable for sanitary hot water systems.

Operating Conditions: The pump operates with liquid temperatures ranging from +5 °C to +65 °C and ambient temperatures from 0 °C to +40 °C. It can withstand a maximum working pressure of 10 bar and is certified to meet CE requirements. The sound pressure level is ≤ 38 dB (A), and it can handle a maximum glycol quantity of 20%.

Motor Specifications: The pump is equipped with a synchronous motor with variable speed, operating at a standard voltage of single-phase 230 V and a frequency of 50 Hz. It has an IP 44 protection rating and insulation class F, with integrated overload protection.

Special Features: An optional NCE PR version includes an additional module for analog signal control (0-10V). Brass unions are available on request.

Designation: The pump series is designated as NCE PS, with variations indicating the DN ports in mm, maximum head in dm, and connection size in mm.

Adjustment and Use: The pump features easy adjustment with an LED indicator and offers three proportional curves and three fixed speed curves, selectable via a button.

Operating Modes: The pump can operate with proportional pressure curves or fixed speed curves, with LED indicators showing the selected mode.

Dimensions and Weights: The document provides detailed dimensions and weights for various models, including NCE PS 20-40, 25-40, 20-60, 25-60, 20-80, and 25-80.

Materials: Key components include a bronze pump casing, composite impeller, ceramic shaft, carbon bearings, ceramic thrust bearing, stainless steel jacket rotor, copper wire winding, and EPDM gasket.
