What are the benefits of an integrated frequency converter?

An integrated frequency converter allows for precise, continuously variable control of motor speed, enabling the pump's performance to be adapted to specific system requirements and potentially reducing energy consumption.

Is this pump suitable for food-grade applications?

Given that all wetted parts are typically stainless steel, units of this type are often suitable for handling potable water and various liquids within food processing, but buyers should confirm specific material grades and certifications with the seller.

What kind of maintenance does this pump require?

Maintenance typically involves periodic checks of the cartridge shaft seal and motor, with the cartridge design simplifying seal replacement. The integrated control system may also require occasional software or parameter checks.

Can this pump be integrated into an existing control system?

Yes, units of this type commonly feature terminals for remote start/stop, analog setpoint signals (0-10 V, 0(4)-20 mA), and sensor inputs, facilitating integration with external control systems or building management systems.

What does 'multistage' mean for a centrifugal pump?

A multistage pump has multiple impellers in series, which allows it to generate higher pressures compared to a single-stage pump of similar size, making it suitable for applications requiring significant head.

Used Equipment New Grundfos Pump - Vertical, multistage centrifugal pump with integrated frequency converter. inlet and outlet ports on same the level (inline).

The pump head and base are in cast iron – all other wetted parts are in stainless steel.

A cartridge shaft seal ensures high reliability, safe

handling, and easy access and service. Power transmission is via a rigid split coupling. Pipe connection is via DIN

flanges.

The pump is fitted with a 3-phase, fan-cooled asynchronous motor. The motor includes a frequency converter and PI

controller in the motor terminal box. This enables continuously variable control of the motor speed, which again

enables adaptation of the performance to a given requirement. An operating panel on the motor terminal box enables

setting of required setpoint as well as setting of pump to "Min." or "Max." operation or to "Stop". The operating panel

has indicator lights for "Operation" and "Fault".

Communication with the pump is possible by means of Grundfos GO Remote (accessory). The remote control

enables further settings as well as reading out of a number of parameters such as "Actual value", "Speed", "Power

input" and total "Power consumption".

The terminal box holds terminals for these connections:

pump start/stop input (potential-free contact)
remote setpoint setting via analog signal, 0-10 V, 0(4)-20 mA
10 V voltage supply for setpoint potentiometer, Imax = 5 mA
three analog sensor inputs, 0-10 V, 0(4)-20 mA
24 V voltage supply for sensor, Imax = 40 mA
one analog output
three digital inputs
two Pt100 inputs
two potential-free fault signal relays with changeover contact, reporting "Fault", "Operation" or "Ready"
RS-485 GENIbus connection
interface for Grundfos CIM fieldbus module
