It flows along its entire length the Yamal-Nenets Autonomous District, in parts strongly meandering through the swampy, lake-rich and forested lowland in the east first, then northeasterly to northerly direction. Finally, it combines four kilometers below the town Tarko-Sale with Aiwassedapur to Pur.
Its main tributaries are Wyngapur (also Wengapur ) from the right and from the left Purpe.
The catchment area of 31,400 km ² comprises Pjakupur. The average discharge at the mouth at close Tarko-Sale 307 m³ / s. , With a minimum monthly average of 98 m³ / s in March and a maximum monthly average of 1122 m³ / s in June Near the confluence of the Pjakupur is about 250 meters wide and two meters deep. The flow rate is in this case 0.9 m / s
The river freezes from October to late May / early June.
Economy and infrastructure
The Pjakupur is navigable in the lower reaches to 85 kilometers.
In the catchment area of the Pjakupur are important oil and gas deposits, as Gubkinskoje, Wyngajachinskoje, Wyngapurowskoje, Sutorminskoje, Murawlenkowskoje ( at Muravlenko ) Komsomolskoje, Barsukowskoje, Nowopurpeiskoje and Umseiskoje.
