格睿司® 850系列产品工业水泵

1Flanged Iron Casing

The 850 Series iron casing is tapped for a drain, vent and pressure gauge. It includes a suction wear ring and can be rotated to various discharge positions. Standard ASME B16.1 flange-type suction and discharge nozzles facilitate installation and maintenance.

2Renewable Lead-Free Bronze Shaft Sleeve

The renewable lead-free bronze shaft sleeve insulates the shaft from abrasion and contact with pumped liquids.

3Mechanical Shaft Seals

Mechanical shaft seals feature Carbon/Ceramic/Buna-N and Stainless Steel components, eliminating maintenance and adjustment problems.

4Renewable Lead-Free Bronze Wearing Rings

Precision-made lead-free bronze wearing rings are pressed into the casing and/or adapter as required and are renewable, as well as easily replaced in the field.

5Single-Piece Enclosed Impeller

Made of aluminum bronze and keyed to the shaft, the single-piece enclosed impeller is precision balanced with the diameter cut for the specific condition point. On high-head units, the impeller back is drilled for hydraulic balance, limiting thrust load and reducing pressure in the sealing area. Aluminum bronze is a preferred material over stainless steel for its durability and superior corrosive resistance, especially in chlorine applications.

6Power Frame

Designed to ASME B73.1 Specification.
