Series description

Design

Highly efficient high-pressure multistage centrifugal pump in vertical design with in-line connections, VdS certified for use as sprinkler pump in stationary water extinguishing systems.

Equipment/function

Use of different pump housing connections is possible which is available on Helix standard pump ranges. The material of pump housing shall have the elongation at break at least 15%.

Wilo-Helix FIRST pumps are VdS certified up to 110 m delivery head. These pump versions are not allowed to exceed the defined delivery head and the allowable pressure 12 bar. Wilo-Helix FIRST pump housing is made of cast iron GJL250. VdS requires JL1040 or at least equivalent material as sufficient.

Wilo-Helix VF and Wilo-Helix FIRST VF fulfil the VdS requirement of non – rusting metal with a melting point > 800 °C for pump shafts, shaft protection sleeves, impellers, impeller mounting components and wear rings.

The connection of pumps and motors shall be made separately by a coupling. The power provided by the motor must be sufficient for the H(Q) curve. Overload values or values for short time operation are not allowed on VdS certified Helix series. The torque of the drive motors shall be greater as the counter torque exerted by the pump all the way from standstill to rated speed. The motor power and overload is found at power peak 5% and at 16m NPSH.

Qzul means Q zulässig. This is a German description for permissible delivery flow. The duty point must not be at the right of this limit. When delivering at 1.2 times the permissible delivery flow, an NPSHR of 5.5 m shall not be exceeded.

The formula used for Qzul:

Q4.5mNPSH times 1.2 must not exceed Q5.5m NPSH, in this case Qzul = Q4.5m NPSH.

If the result exceed the value of Q5.5m NPSH then Qzul is Q5.5m NPSH/1.2.

Wilo SE must conduct a pressure test with each pump casing in finished condition or in assembled condition. Each Helix VF and Helix FIRST VF is to test in assembled condition:

  • Test medium: water
  • Test pressure: 1.5 times allowable pressure
  • No signs for breaks/ cracks or inadmissible plastic deformation is visible during and after the test

Technical data

Basis of VdS approval:

  • VdS 2344:2014-07
  • VdS 2100-07:2013-05

The VdS approval No. is P 418007

Materials

Wilo – Helix VF pump types VdS certified are available in AISI304 and AISI316L. The pumps are available with standard mechanical seal or cartridge mechanical seal. Wilo-Helix VF and Wilo-Helix FIRST VF fulfil the VdS requirements for seal materials such as for example EPDM, FKM.

Construction

The non self-priming high-pressure multistage centrifugal pump has a particularly compact overall design. The pump shaft and the motor shaft of the IEC standard motor are connected by means of a clamp coupling. A separate lantern

roller bearing ensures optimum admission of axial thrusts.

Intermediate bearings in the hydraulics and corrosion-resistant shaft due to stainless steel sleeve ensure a long service life. Special, permanently attached lifting eyes enable easy pump installation.

The marking of the pump is non-detachable, non-flammable and permanent.
