This design was running from the long time. But we had just entered this design, it is also made in the 2 types of the design.

HH type- It is basically the same from the outer side but different from inside. The Impellor used in the HH type is the fabricated one. This Impellor has its own plus point. It has higher efficiency than its rival that is heavy type. Moreover the head also gets increased by marginal amount.

Heavy type – This is an one of the oldest design that is used by the industry. It has the ss Impellor. It increases the life of the pump.
