耦合型

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.

配件選型

EFG_Configurations

緊密耦合或框架安裝配置

850系列泵隨附NEMA JM或JP耦合電機。作為替代方案，格睿司可為電機提供彈性聯(lián)軸器，包括開式防滴型電機、全封閉電機和防爆電機、或發(fā)動機、蒸汽輪機和皮帶驅(qū)動選件。

EFG_Seal-Options

密封選件

雖然我們的標準機械密封由碳/陶瓷/丁腈橡膠組成，但我們還可以為更具研磨性/腐蝕性和高溫應用提供替代方案。

EFG_Mounting-Systems

涂層選項和底板安裝系統(tǒng)

為防腐蝕，850系列泵可在內(nèi)外部涂上3M?Scotchkote?134熔結(jié)環(huán)氧樹脂。格睿司還提供一整套預加工的槽鋼底板，以減少應力和振動。
