AHLSTAR WPP/T wear-resistant process pump rangeAHLSTAR WPP/T wear-resistant end-suction single-stage centrifugal pumps are designed for abrasive and erosive pumping applications, such as lime milk and mud, and coating pigments. The pump exceeds the requirements of ISO 5199.
Sulzer ejector for fully automated sump pumping
Reliable and cost-effective sump pumping with Sulzer’s ejector
The alternatives were to use a cantilever pump, a submersible pump, a self-priming process pump or a process pump with an ejector
We needed to find the optimal solution for sump pumping in terms of reliability, service friendliness, efficiency and investment costs to maximize the benefits for the customer.
The customer wished to use a standard process pump for sump pumping to enable the use of the same spare parts as for the process pumps in the other applications of the mill.
We concluded that our SNS process pump provided with an ejector was clearly the best alternative for this purpose – both energy efficient and cost competitive. We were able to select from a variety of pump sizes and stated that the SNS1-80 pump was performing very efficiently, and that the ejector did not consume energy during the normal pumping process. In the mill, there was pressurized air available for the ejector.
The wastewater pit pump works intermittently, so priming is needed multiple times per day. The automation package controls the valves accurately and performs the priming smoothly. No problems or failures have occurred. Priming with an ejector is efficient, reliable and fast.
Sump pumping has never been as easy as with a standard process pump equipped with an ejector. Priming has never failed, and it is very fast.
Area Sales Manager at Sulzer in Finland
- The complete pump unit and the ejector, including the automation package, were easy and fast to install and take into use.
- The ejector makes sump pumping easy, fast, reliable and cost effective.
- The investment cost is low.
- The solution is service friendly because the sump pump uses the same spare parts as the other process pumps in the mill.
