3 PXA and PXK Electrical design The drive motors meet VDE regulations as well as European motor standards (DIN EN /02.99) and the requirements underlying the CE mark. Designs in conformity with non-european regulations, e.g. CSA, UL or special requirements, e.g. the USA or Japan, are possible. Degree of protection:..... IP 55 (DIN EN /4.88) Direction of rotation:.... clockwise as viewed from above looking down on the motor's ventilation side. Insulation class: F Ambient temperature:.... max. 40 C (DIN EN /02.99) at a max. of 1000 above sea level Electrical parameters kw: 230/400 V, 50 z 265/460 V, 60 z > 4 kw: 400 V, 50 z 460 V, 60 z Installation and operation Other mains voltages on request. Suitable in the standard version for vertical installation in the reservoir. Other installation situations available on request. When the pump is switched on the minimum level of fluid has to be above the bottommost pump chamber ➀. The pump then delivers all the way to the intake in the chamber or tube ➁. The maximum permissible level of fluid amounts to 30 mm below the reservoir's cover ➂. Versions: with empty intermediate chambers with extension tube Type key Model PXA - up to 25 bars PXK - up to 7 bars Motor size 02 = 2 m 3 /h 04 = 4 m 3 /h Number of stages See the tables for details Material type = cast iron (standard) Seal type B = ap bush = Mechanical seal Pump type S = basic outfitting V = prepared for extension tube Immersion depth See the tables for details Motor index See the tables for details Electrical data 01 = 230/400 V 50 z; 265/460 V 60 z (standard up to 4 kw) 02 = 400/690 V, 50 z; 460 V, 60 z (standard after 5.5 kw) Andere Netzverhältnisse auf Anfrage Motor type AA = Standard (insulation class F, IP 55, 2-pole type) AI = Motor with frequency converter AC = UL /CSA version AD = Industrial connector (DESINA) Sectional drawing PXA PXA B S 185 D 01 AA ➂ ➀ ➀ ➁ Fig.: different delivery characteristics at the same immersion depth.
