Multistage Pumps

Grundfos CR-Pumps

The basic pumps CR pumps range, which can be applied in almost any industrial solution, is already in itself the broadest range available. Through our modular approach, we have made it even broader.

The basic CR pumps range is available in four different materials: cast iron, two grades of stainless steel, and all-titanium. There are eleven flow sizes pumps, capable of producing up to almost 50 bar of pressure, and with a variety of shaft seals, rubber materials and supply voltages.

Grundfos Pumps Water Treatment

Grundfos Pumps Water Treatment Overview

Even with Grundfos Pumps Water Treatment a good water source, Grundfos Pumps Water Treatment should be considered to ensure a good water quality. Grundfos Pumps Water Treatment describes those processes used to make water more acceptable for a desired end-use and to ensure that stringent quality standards to the consumer are maintained. Grundfos can supply pumping solutions for solids separation using mechanical treatments such as settling and filtration, dosing solutions for chemical treatments such as disinfection and coagulation.

For example, dissolved substances that are removed during drinking Grundfos Pumps Water Treatment include calcium and magnesium from hard water, sulphur and carbon dioxide from acid water, iron from red water, manganese from brownish-black water, nitrate from fertiliser-contaminated water, hydrogen sulphide gas from rotten-egg smelling water, and sediments and organic matter from turbid water, where minerals may also be dissolved in high concentrations. Other desired end-uses for water could be for industrial processes or medical use.

Grundfos Pumps Water Treatment systems range from submersibles to end-suction pumps and huge split-case pumps as well as our highly successful vertical multistage centrifugal pump (CR). Grundfos Pumps Water Treatment Our complete range of dosing pump systems are for large or small volumes and based on different technologies; electronic and electrochemical accessories offer complete control; and PLC-controlled, fully automatic systems for dry material preparation and reliable dosing.

The sustainability of Grundfos Pumps water treatment solutions requires that the pumping solution is durable, ensuring cost effective and trouble-free operation. Grundfos has decades of experience developing controller and monitoring systems for pumping solutions and manufactures its own pump motors for all fluid types and flow requirements.

External frequency converters (CUE) for variable speed drives and motor protection (MP204) to monitor motor conditions ensure optimal adaptation to changing conditions. This ensures a perfect match with hydraulics, motors, electrics, and all other mechanical components Grundfos Pumps Water Treatment that make up a comprehensive pumping solution, ensuring the best possible efficiency point.

Grundfos Pumps Water Treatment solutions are designed specifically for pumping installations and all the components are fully integrated from the outset. Life Cycle Cost analyses have shown how this seemingly complex and costly process results in tangible benefits for owners. Grundfos Pumps Water Treatment commissioning agreements ensure correct installation and service agreements cover all eventualities, from routine maintenance to spare parts and pump audits.

Menjual Pompa Air Industri

banyak macam-macam produk pompa yang kami jual, dengan kualitas dan penggunaan  bahan-bahan yang aman, menjadikan pompa yang kami jual sangatlah handal dan memiliki daya tahan kual, kami mangajak setiap konsumen untuk menghemat penggunaan air bersih dengan memakai air bersih sesuai kebutuhan saja.

CR YANG TIDAK TERTANDINGI

Grundfos adalah produsen pompa pertama yang membuat pompa in-line multistage, dan kami selalu menyempurnakan disainnya terus menerus. sekarang, pompa CR tersebut menjadi sangat populer, tidak tertandingi kehandalan dan efisiensinya. Grundfos CR tersedia dalam stainless steel atau titanium dengan 13 ukuran kapasitas dan ratusan ukuran tekanan. pompa CR 150 dengan motor 75 kW adalah pompa CR terbesar yang ada di pasaran. dan seluruhnya dengan disain modular dengan kemungkinan lebih dari satu juta konfigurasi.
Fitur efisiensi yang ditambahkan
Pompa CR Grundfos mengintegrasikan motor EFF1-standard yang menggerakan pompa dengan konsumsi listrik minimum yang bisa dilakukan. lebih dari itu, teknik pengelasan laser mampu mengurangi turbulens pada implleller, yang juga menurunkan 10-15 persen konsumsi listrik.
Lupakan kerusakan akibat dry-running
Grundfos LiqTec yang sudah kami patenkan langsung mematikan pompa jika pompa bekerja tanpa air.
Mengurangi downtime
 Downtime adalah biaya. Shaft seal merupakan penyebab 3 kerusakan dari 4 kerusakan yang mungkin terjadi. jadi Grundfos telah mengembangkan cartridge unik dengan disain yang mudah dipasang sehingga pergantian shaft seal hanya membutuhkan waktu beberapa menit saja.

General notes – ErP (ecological design-) directive

 

  • The benchmark for most efficient water pumps is MEI ≥ 0.70
  • The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter.
  • The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.
