High-efficiency circulation pump WITA Delta HE light 60-32-130

Product detailed description

The circulation pump WITA Delta HE light 60-32-130 belongs to the range of high-efficiency pumps with a permanent magnet motor in EC technology. According to the type designation, it is a version with a DN 32 connection and an installation length of 130 mm. The first number (60) is related to the hydraulic performance and distinguishes this type from other versions of the Delta HE light range.

The manufacturer WITA states that standard conventional pumps cause an average of 10 to 15 % electricity consumption in a typical household. With high-efficiency WITA pumps, energy consumption can be reduced by approximately 80 % compared to a standard circulation pump, while the hydraulic performance can remain almost the same.

Main Features

• EC motor with permanent magnets for maximum efficiency
• minimum power consumption from 3 W
• menu controlled by a single touch
• preselected regulation modes: constant speed or variable differential pressure
• Anti-block function
• integrated motor protection
• high safety at startup
• easy installation on the pipe thanks to practical key mounting

Material and Delivery

WITA uses cast iron body with cathodic coating and chrome-nickel steel in production, which according to the manufacturer ensures high durability and versatile use. The pump body is made of gray cast iron with cathodic coating for installation lengths of 130 mm and 180 mm, while the 110 mm version is made of brass. The type 60-32-130 with a length of 130 mm therefore belongs to the cast iron variants. Pumps are delivered with thermal insulation jackets, gaskets, connecting plugs or permanently installed cables.

Control

With a single touch, one of eight performance curves can be selected: four are constant and four are proportional. The proportional characteristics operate on the principle of variable differential pressure, in which the pump adjusts the head to changes in flow, for example when valves in the circuit are gradually closed. In the constant speed mode, the pump, on the other hand, operates along the selected curve independently of these changes.

Technical Data of the Delta HE light Range

The table includes the manufacturer's data for the entire range. The maximum head and flow may vary for individual types, so when dimensioning, refer to the type designation 60-32-130 and the pump documentation.

Application

The circulation pump ensures water circulation in a closed circuit. According to the technical data, it can withstand a medium temperature from +5 °C to +110 °C and a system pressure up to 10 bar, while the ambient temperature can be from 0 °C to +40 °C. The protection class IP 42 and temperature class TF 110 determine in which environment and at what temperature the pump can be operated.

Installation

The pump is easily attached to the pipe using a key. Before installation, check whether the installation length (here 130 mm) and the connection size match the existing piping, and follow the flow direction and mounting position specified by the manufacturer. Use thermal insulation jackets and gaskets in accordance with the instructions.

Frequently Asked Questions

What does the designation 60-32-130 mean?

This is the type designation of a specific version of the Delta HE light range. The middle number 32 corresponds to the connection size DN 32 and the last number 130 to the installation length of 130 mm, the first number is related to the hydraulic performance.

Does the pump require separate motor protection?

No, the pump has integrated motor protection and external protection is not required.

Which regulation modes can I choose?

Constant speed or variable differential pressure. In total, eight characteristics are available, four constant and four proportional.
