1. General Description
Transport the sand or pebbles or applied with big capacity with high head and single casing constructure.
2. Introduction
NS (G) series gravel pumps are horizontal and single-casing centrifugal pumps. The type NS (G) pumps are of high-head ones. Construction of this pump is of single casing connected by means of clamp bands and wide wet-passage. The wet-parts are made of Ni-hard and high-chrome wear-resistant alloys.
The discharge direction of pump can be oriented in any direction of 360. This type of pump owns the advantages of easy installation, good performance of NPSH and wear-resistance. The standard seal type is packing seal.
3. Model Explanation 
  NS (G) - 8S
  N: Our company(Norman)
  S: Sand
  G: High head
  8: Discharge size (inch)
  S: Frame type with maximum power
 

Note:1. Quantity range recommended: 50%Q’≤Q≤110%Q' (Q' Appropriate to capacity at highest efficiency point).
2. NPSH: appropriate to point Q recommended at highest speed.

Application Gravel pumps are designed for continuously handling the most difficult higher abrasive slurries, which contain too big solids to be pumped by common pumps. They are suitable for delivering slurries in mining, explosive sludge in metal melting, dredging in dredger and course of rivers, and other fields.
