Marine Fire Pump Impeller Introduction

The marine fire pump impeller is the one of the key parts for the fire pumps. The right selection of the impeller material would effect the efficiency and operation of the fire pump system.The impeller material selection would be one the most important point we have to pay attention to.

Generally, the fire pump material is stainless steel. In terms of material price, corrosion resistance of stainless steel is a good choice for fire pump. Stainless steel can be immersed in acid-alkali solution for a long time without being corroded. Its surface is smooth and hygiene. Even in other fields. stainless steel can replace aluminum alloy impeller for food hygiene. Because of the humidity of the
environment some fire pumps will cause rust over time.

If the impeller is made of bronze impeller, it is not only bulky. but also easy to be hindered by corrosion, resulting in the loss of the rotational efficiency of the impeller. For long-term use and efficiency, stainless steel is the best selection for fire pump impeller. We can also provide other materials, such as casting iron, casting bronze, stainless steel 304/316. All products are customized according to your drawing and requirements.

Marine Fire Pump Impeller Types

Type	Feature
Closed Impeller	u There are cover plates on both sides of the closed impeller, and there are 6 blades between the cover plates. The closed impeller has high efficiency and is the most widely used. It is suitable for conveying clean liquid without solid particles and fiber.
Semi-open Impeller	u The open impeller has no cover plate on both sides of the blade, so it is suitable for conveying liquid containing a large amount of suspended solids, the efficiency is low, and the liquid pressure is not high.
Open Impeller	u Semi-open impeller this impeller has only the rear cover plate, it is suitable for conveying liquids that are easy to precipitate or contain solid suspended matter, and its efficiency is between the open impeller and the closed impeller.
