Facilities must be in place to enable safe on-site refilling, with no environmental risk and no loss of time. Tolsma Tanks has created a pump set for all tank users which fulfils these requirements, ranging from simple vane pumps to high-capacity double pump sets. There are also suitable pump sets available for AdBlue users. All Tolsma pump sets are equipped with the Tolsiph anti-siphon valve and Petro Clearfilter for problem-free refilling.
