SPEL Penstocks

The penstock is a standardised penstock with sizes up to a diameter of 2000 mm to meet pressures of up to 5 meter water column both on- and off seating.

Penstocks can also be supplied for rectangular openings, with or without a flush invert bottom. On request we can also supply penstocks with higher water pressure.

SPEL penstocks are made of a combination from HDPE and stainless steel. Because of his characteristics, HDPE has a lot of advantages, compared with the use of traditional materials.

HDPE is corrosion free, has good chemical resistance, low density and lightweight, high flexibility and easy to machine. This results in a product that has a very long service life. Furthermore, no special coatings are needed. It is very flexible in design and easy to handle. Ensuring minimal maintenance and the highest user friendliness.
