Wilo Wilo-VeroLine-IPL
Wilo single-stage in-line pumps with dry rotor and mechanical seal, for heating water, chilled water and water-glycol mixtures.
Wilo-VeroLine-IPL is a low-pressure, single-stage centrifugal pump in in-line construction, with a dry rotor sealed by a mechanical seal, threaded or flanged connection and a motor with a one-piece shaft. It pumps heating water treated to VDI 2035, chilled water and water-glycol mixtures without abrasive substances, in heating, chilled water and cooling installations. The casing and lantern are in EN-GJL-250 cast iron, the impeller in glass-fibre-reinforced PPO or EN-GJL-200 cast iron, depending on the pump type, and the shaft in 1.4021 steel; the flange has an R 1/8 pressure measuring port.
The code has the form IPL 40/160-4/2: 40 is the nominal diameter of the connection, 160 the nominal impeller diameter, 4 the rated motor power P2, in kW, and 2 the number of poles. For a quotation, send us the code from the nameplate, the Wilo article number, if you have it, and the pressure rating of the installation. When the item is available locally or at the supplier, delivery takes 24–72 h, and on order usually 1–4 weeks.

Frequently asked questions
What does the code IPL 32/135-1,5/2 mean?
32 is the nominal diameter of the connection, 135 the nominal impeller diameter, 1.5 the rated motor power P2, in kW, and 2 the number of poles.
Up to what pressure does the IPL pump work?
The standard design works up to 10 bar. For 16 bar there is the special design with a PN 16 casing (variant -H5), and variant -H4 has PN 6/10 flanges.
What data do you need for a replacement IPL pump?
The code from the nameplate, the supply voltage, the pressure rating and the pumped liquid, especially if it is a water-glycol mixture. If the nameplate is missing, the flow, the head and the distance between the flanges help us.
Other Wilo series
We quote the VeroLine-IPL pump by the code on the nameplate and by the pressure rating; hydraulic sizing and installation of the pump are outside our quotation.
