Pump choice
If a customer can choose a pump in accordance with the flow and head diagrams, then the customer only needs to state the connection type designation and the seal type number.
For example: Chemical centrifugal pump with thread connections without additional cooling of the mechanical seal PIB-42.N3. Please note that the flow and head diagrams are obtained by water testing. If our standard pumps do not meet the requirements of our clients (due to the electric motor, seal, connection joints, etc.), this should be mentioned in the inquiry. We will do our best to solve the problem by modifying the existing pump designs or by making new special designs. If a set of spare parts is ordered with a pump, the set number should be quoted.
Set I - 1 off mechanical seal and 9 other seals in the impeller.
Set II - Set I plus. This set is for our customers who have a large number of our pumps in their plants. It contains 5 mechanical seals and 13 seals for the impeller.
Set III - Set I plus pump rotating part , including a shaft and a shaft nut, a rotor and a rotor nut.
Set IV - Set II plus a rotor and rotor tightening nut. This set is for customers who have many of our pumps in use.
