Weir Specialty Pumps applies advanced pump design technology to increase product performance, reduce cost and improve lead time. The long-established screw centrifugal design provides clog-resistant pumping for trouble free movement of solids, and fibrous and stringy materials. The steep head-capacity curve produced by the impeller provides additional head to help push through any partial blockages.

Low NPSH: The screw portion of the WEMCO® Screw Centrifugal impeller performs as an inducer, pulling liquid into the impeller, resulting in low NPSH requirements. Solids Handling: The single vane impeller of the WEMCO® Screw Centrifugal pump creates a single channel flow, allowing for larger solids passage. The large solids passage provides better solids handling capabilities than any other pump type. The steep head-capacity curve provides ample reserve pressure to clear temporary clogs. Sludge Handling Positive Suction: The combination of a low NPSH requirement and large solids channels provides a powerful pump for handling thick sludges.
The steep head-capacity curve of the WEMCO® Screw Centrifugal pump also allows for pumping of varying sludge consistencies without the need to change speed. An additional benefit is the reserved head for clearing temporary line blockages. Adjustable Liner: Consistent impeller to liner clearance is imperative to the performance of the pump.
As the pump components wear, clearance between the impeller and liner can be adjusted to ensure optimal performance.

Despite being at one of the lowest price points of any of the the rods in this list it is still a terrific rod that is massively popular. Saying that, there are some exceptional high quality rods out there as alternatives to the Ugly Stik. Manufacturers like St Croix, G Loomis and Abu Garcia have built massive trust amongs fishermen for their brands and that trust is usually hard earned. Spinning fishing combos. Ugly Stik have managed to create an even better trout rod than the much loved original GX2 series of rods. This upgraded version has proven itself time and time again as one of the best value ultralight spinning rods available.

Hidrostal Process Engineering AG » » » Service » » HIDROSTAL Service (2) Consideration of the optimal material combinations and lower life cycle costs determines the design of each Hidrostal pump. Hidrostal distributors also meet the Hidrostal quality demands with regard to competent consultation, project work, commissioning and maintenance of Hidrostal pumps. Frequent intense training programs for the Hidrostal product managers of our partners take place in our headquarters in Neunkirch. Experience of many years with Hidrostal products with the Hidrostal sales and engineering departments guarantees a high quality standard for applications. Installation and Commissioning Hidrostal pumps are always supplied with an extensive operating and maintenance manual. These manuals describe all steps for installation and commissioning in detail. In case of any questions, please contact our service department at the factory in Neunkirch or the closest local service center in your area.
Upon request we will also install and commission your Hidrostal pump on site. Our sales engineers, service engineers and local service partners are at your disposal any time. Examination and maintenance Hidrostal pumps can ideally be operated with less comprehensive maintenance work.
Upon request, preventive service work like application audits of our pumps installations to minimize possible downtimes can be done by our personnel or service partners. Please contact the service partner nearest to your company to coordinate your individual requirements.
DESIGN PHILOSOPHY Hidrostal’s philosophy is to blend innovative ideas with well tested pump designs, to produce value for money products to minimise the life-time cost of ownership. The objective of the design process is to:. Make available a range of build options to suit a wide variety of applications.
To maintain interchangeability across all generations of pumps. This flexibility permits sub-assemblies like hydraulic ends, bearing frames and submersible/ immersible motors to be exchanged at any time to allow the users to take advantage of the latest dev-elop-ments in pump technology. The possibility to upgrade the specification at any time for changing operating conditions.
THE SCREW CENTRIFUGAL IMPELLER All Hidrostal pumps incorporate the company’s Screw Centrifugal Impeller. Extremely versatile in its applications, the impeller provides efficient handling of a range of liquids, often highly abrasive or corrosive in nature. It is ideal for:. Solids Handling. Pumping Viscous Sludges.
Handling Delicate or Low Shear Products Unique to all Hidrostal pumps is the ability to handle the above in combination. Many applications too arduous for other types of centrifugal pumps can usually be handled by the Hidrostal screw centrifugal impeller. The impeller comprises a single spiral vane, having large open passages, which makes a long slow turn from the axial inlet to the radial outlet. The design provides optimum hydraulic performance giving:.
High efficiencies. Steep and stable hydraulic curve. Non-overloading power curve.
Low NPSH. Non-clog pumping. Typical applications:. Industrial effluents.
Raw unscreened sewage. Viscous sludges. Return activated sludges. Drainage/Stormwater. Process Waste. Hidrostal immersible pumps are a versatile, innovative development of the established submersible range. Capable of continuous operation in a dry installation, the immersibles may be operated, with equal efficiency, when fully or partially submerged.
The pumps are particularly suited for dry pit applications where the combination of the Screw Centrifugal Impeller and immersible motor can be considered the state-of-the-art technology. Leakage of the pumped product is eliminated by tandem seals running in an oil bath, avoiding a situation commonly experienced with soft-packed glands. Hidrostal immersible waste water / sewage pump stations have fre-quently been mistaken for clean water stations, due to the lack of odour and the cleanliness of the buildings. Immersible pumps are particularly suitable for installation where quiet running, clean surroundings, reliable and long trouble-free operation is required. The pumps may be installed vertically or horizontally.
Profile Hidrostal Pumps markets, sells, supports, assembles and services Hidrostal products for the North American market. We carry an inventory of parts, assemblies and motors to serve our customers for new orders and aftermarket. History Hidrostal pumps have been sold in the United States since the 1970s. An initial sales agreement was concluded with Wemco/Envirotech in 1981. The Weir Group acquired Wemco in the 1990s and began selling Hidrostal pumps under the Wemco brand.
Weir Salt Lake City (and their predecessor companies) represented Hidrostal in the USA and Canada as a sales partner, but have never manufactured Hidrostal pumps or motors. Based on our sales strategy we decided to form Hidrostal USA in 2015. This decision was part of the ongoing process to better serve our customers and have a more direct relationship to the North American market.
Hidrostal Pumps is located in Aurora, Illinois and cooperates with independent manufacturers representatives and distributors across the USA and Canada. Get the «ORIGINAL» The pumps and motors sold by Weir under the brand name «WEMCO-Hidrostal» or similar were solely produced by Hidrostal. The screw centrifugal pumps and motors currently offered by Weir and branded as «WEMCO» are not designed, manufactured or supplied by Hidrostal, nor do they share the time tested performance of the ORIGINAL Hidrostal products. Please do not be fooled by sales information designed to confuse these facts. We do not assume any warranty or liability for those products nor stand with our good name behind them. Their design and manufacture lies only and exclusively in the responsibility of Weir and have no affiliation to Hidrostal.
