Wilo-SCP Wilo-Sub TWU 3-HS-I Wilo TWU 3-HS-E-CP

Enhanced output due to increased speed (up to 8,400 l/min.) have given the Wilo-Sub TWU 3-HS-I and the Wilo-Sub TWU 3-HS-E-CP the nickname the fast one. The pumps ensure constant high pressure thanks to an integrated or external frequency converter. And all that in 3 inches, which keeps removal and installation costs low. With flexible installation vertically or horizontally, youre sure to be completely convinced.

9General notes and abbreviations


Wear and tearPumps or parts of pumps are subject to wear in accordance with the current technical standards (DIN 31051/DIN-EN 13306). This wear may vary depending on the operating parameters (temperature, pressure, speed, water conditions) and the installation/usage situa-tion and may result in the failure of the above products/components, including their electrical/electronic circuits, at different times.Wear or wearing parts are all components subject to rotary or dynam-ic stress, including electronic components to which voltage is ap-plied, including in particular:

Gaskets (including mechanical seals), seal rings. Stuffing boxes. Bearings and shafts. Impellers and pump components. Thrust rings and wear rings. Wear rings / wear plates. Macerators. Condensers. Relays/contactors/switches. Electronic circuits, semiconductor components etc.

Pumps and continuous-flow machines (such as submersible mixers and recirculation pumps) and their coated components (cataphoretic, 2K or Ceram coating) are subject to constant wear due to the abrasive content of the fluids. For this reason the coating of these units is also counted as a wearing part!

We do not accept any liability for faults or defects arising from natu-ral wear and tear.

Wilo General Terms of Delivery and ServiceThe latest version of our General Terms of Delivery and Service can be found on the Internet atwww.wilo.com

EN-GJS

Cast iron with spheroidal graphite, also referred to as spheroidal cast iron. The use of spheroidal cast iron in domestic water systems is governed by the Drinking Wa-ter Directive 98/83/EC and applicable rec-ognised technical rules and standards!

Thermal overload protection of the motor and the frequency con-verter

The version "HS-E with external frequency converter offers the following additional equipment features:

Control function "CP: Constant pressure Avoidance of frequent switching (cycling) by leakage monitoring Dry-running protection with automatic reset Change of direction of rotation Setting for max. flow and target pressure Pressure is shown on the display Settings, operating statuses and error messages are shown by LEDs

or on the display.

The frequency converter always must be installed outside the fluid where it will be protected against overflows!

Control function "CP: Constant pressureOperation with the frequency converter means the rotation speed of the unit is adapted to the current water requirements automatically. As a result, the submersible pump always delivers a constant pres-sure.

CoolingThe motor is cooled by the fluid. The motor must always be operated in submerged state. The limit values for the max. fluid temperature and the minimum flow rate must not be exceeded. In cases of vertical installation, a cooling jacket must be provided de-pending on the diameter of the bore. In cases of horizontal installa-tion, a cooling jacket must always be provided .

The external frequency converter is also cooled by the fluid. For this the frequency converter must be installed directly in the piping out-side the fluid (overflow-proof).

Options Special cable lengths on request

General notes - ErP (ecological design-) directive The benchmark for most efficient water pumps is MEI 0.70 The efficiency of a pump with a trimmed impeller is usually lower

than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to re-duced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter.

The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the sys-tem.

Information on benchmark efficiency is available at www.europ-ump.org/efficiencycharts
