Successful Pilot Project in Czech Republic
Pump manufacturer Zuwa and its Czech distribution partner PH Gia have developed a solution for large tank trucks using Zuwa’s flexible impeller pumps. PH Gia and a highly specialised tank truck manufacturer just finished the testing period with a Zuwa Nirostar 2001-F.
The set up is used to supply small tank trucks or local tanks with DAM, a 30% aqueous Urea solution used as nitrogene fertilizer in agriculture.
The dry self priminig Nirostar 2001-F does not require pre-filling. The pump is made of high grade stainless steel, impeller and seals are resistant to fluids with high pH values. The liquid fertilizer is discharged with a flow rate of 400 - 680 litres per minute at a pressure of 1.8 bar.
The pump works bidirectional - discharging the DAM in the first step and cleaning the hoses in the second step. This way no fertilizer is lost and the location stays clean. PH Gia s engineer Tomáš Netopil reports the surprise of the customer about the low energy required to change the pump s rotating direction. According to Eng. Netopil the results were so convincing that his customer will use Zuwa impeller pumps for further applications like milk tanks.
