A Pump’s Role in Safe Chemical Transfer: “One important point is the compatibility of the material with the chemical,” “The second factor is, if we use solvents, for example, we must use the appropriate chemical process slurry pump that won’t cause an ignition. This means using Chemical slurry pumps with electric conductive material. The third factor is suction capability.”
In Europe, the most important legislation introduced in recent years has been Registration, Evaluation, Authorization and Restriction of Chemicals—better known as REACH. Implemented in June 2007 by the European Union, REACH replaced 40 existing directives. There are 73 substances on the Substance of Very High Concern (SVHC) candidate list. The regulation puts greater responsibility on the industry to manage the risks of chemicals and provide safety information on the substances. However, REACH remains a work in progress.
One other way that the chemical industry is creating a safer environment is through certifications. Equipment must meet certain standards to gain certification and must be considered safe to handle known dangerous chemicals—such as acids, solvents and caustics. In the past, the CE symbol was the recognized symbol for safety. The CE marking or formerly EC mark, is a mandatory conformity marking for products sold in the European Economic Area since 1993. The CE marking is the manufacturer's declaration that the product meets the requirements of the applicable EC directives. Therefore, Excellence centrifugal slurry Pumps can develop freely in EU market by obtaining the CE certification. On the other side, we can export our products to Europe even worldwide and ensure the normal promotion to any country in EU.

Ralated Article: Gravel pump for Mineral processing
Series ES(G) gravel pumps are horizontal and single-casing centrifugal pumps. The type ESG pumps are with high-head. The pumps work with various speeds and ensure a long life, which meet the different requirements on hard transporting conditions.
ES series Gravel pump structure
Construction of this series of pumps is of single casing connected by means of clamp bands and they have wide 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°. They have advantages of easy installation, good performance of NPSH and
wear-resistance.
Material advantage
The main wear parts in slurry pump are wet parts. Excellence adopts many kinds of anti-abrasive materials to extend the lifetime of wet parts.
The wet parts material in standard ES series pump is high chrome alloy KmTBCr26, which is a wear resistant white iron that offers excellent performance under erosive conditions. But in order to meet different requirements, Excellence can also produce wet parts in other materials to replace high chrome alloy such as Hastelloy, CD4MCu, and other anti-abrasive materials.
Application
Gravel pumps are designed for continuously handling the higher abrasive slurry, which contain too big particles to be pumped by common pumps. Gravel pump are suitable for delivering slurry in mining, explosive-sludge in metallurgy, sand mining, dredging, and other fields.
