Submersible Pump- DWK and DPK

DWK and DPK are submersible pumps designed for dewatering and drainage applications. The cast-iron construction and the hydraulic design contribute durability and high efficiency. The differences between the DWK and DPK pump ranges lie in the discharge arrangement and the installation type. The DWK is designed with a top discharge pipe and suction strainer, and is thus more suitable for temporary installation, whereas the DPK has a side discharge and a ring-stand or auto coupling (as accessories), and is suitable for permanent installations.

Applications

DWK/DPK are excellent pumps for dewatering and draining applications. The combination of compact design with high-pressure capability makes the pumps suitable for use in pits, whether for temporary or fixed installation. The installation design options provide the flexibility needed to cover many needs. Applications include:

  • Construction sites
  • Excavations
  • Tunnels
  • Fish ponds
  • Drainage pits.

Features and benefits

  • Durability
  • High efficiency
  • Installation flexibility
  • High-pressure capabilities, cost-effectiveness.

Benefits

  • Durability
  • High efficiency
  • Installation flexibility

Pompa Jockey

Pompa Jockey

Pompa Jockey berfungsi untuk menjaga tekanan stastis di dalam jaringan hydrant. Pada saat terjadi pengeluaran kecil atau kebocoran, maka pompa jockey akan bekerja secara otomatis untuk mengembalikan air pada tekanan semula yang direncanakan. Kondisi pompa jockey juga dimanfaatkan untuk memantau kebocoran-kebocoran yang terjadi.

Operasional kerja pompa jockey didesain secara otomatis untuk bekerja (start) pada saat salah satu katup pengeluaran dibuka atau bila terjadi kebocoran. Dan akan berhenti (stop) pada saat katup ditutup.

Secara umum sumber penggerak pompa jockey didapatkan dari listrik PLN atau sistem kelistrikan utama.

Pompa Air Centrifugal.

Pompa Air Centrifugal

Salah satu jenis pompa pemindah non positif yang kerjanya mengubah energi kinetis (kecepatan) cairan menjadi energi potensial (dinamis) melalui suatu impeller yang berputar dalam casing. Prinsip kerja pompa air sentrifugal bekerja berdasarkan prinsip gaya sentrifugal yaitu bahwa benda yang bergerak secara melengkung akan mengalami gaya yang arahnya keluar dari titik pusat lintasan yang melengkung tersebut. Besarnya gaya sentrifugal yang timbul tergantung dari masa benda, kecepatan gerak benda, dan jari-jari lengkung lintasannya.

Tsurumi Pump - NH Series

Pumps with Channel Impeller

NH_Tsurumi-Pump

Discharge Bore(mm)

50 – 150

Motor Output(kW)

1.5 – 7.5

The NH series is a cast iron made, submersible wastewater pump utilizing 2-pole motor. This impeller is a shrouded two-channel impeller. Each channel is designed to have a larger area and it enables the pump to be suitable for pumping wastewater containing a certain size of solids. The pumps are available in six motor sizes ranging from 1.5 to 7.5kW and available in either High-Head or High-Volume Type.

Grundfos - Split Case pump

The Grundfos HS horizontal split case pump is a single-stage, non-self-priming, between bearing, centrifugal volute pump. The axially split design allows easy removal of the top casing and access to the pump components (bearings, wear rings, impeller, and shaft seal) without disturbing the motor or pipework.
The independent bearing housing allows for ease of maintenance without removing the top casing. The double volute design reduces the radial load on the shaft, extending component life, minimising vibration and providing quiet operation.
The HS pump also offers high pump efficiencies throughout the range.  High energy efficiency along with long pump life and easy maintenance add up to low life-cycle costs.
The HS pump is available in three configurations – pump with motor and baseframe, pump with baseframe, and bare shaft pump only.
The HS pump is ideal for custom applications and is available in a wide range of variants. The high efficiency and low life cycle costs make the HS ideal for any commercial building, water utility or industrial project.

Applications Pump

Grundfos HS horizontal split case pumps are typically used in these applications:

  • Air-conditioning/heating systems
  • Public water supply
  • District cooling/heating plants
  • Cooling systems
  • Public waterworks
  • Process cooling
  • Irrigation.

Features and benefits Pump

  • Easy to service: split case design
  • Double suction minimises axial load,which extends the life of the wear rings, shaft seals and bearings
  • Double volute reduces radial forces and minimises noise and vibration
  • Independent bearing housing design allows access to the pump components without removing the top half of the casing
  • High energy efficiency
  • Low life-cycle costs
  • Many product variants available.

Saving Energy - Grundfos Pumps

saving-energy-grundfos-pumpsALL YOU NEED TO KNOW ABOUT PUMPS AND ENERGY THIS IS FOR Saving Energy – Grundfos Pumps

 

 

Pumps are involved in nearly every aspect of modern living. They are used to move fluids such as liquids, slurries or gasses.

Saving Energy – Grundfos Pumps.

In businesses, buildings, households and industries, pumps exist – in some form or another. They are key components in maintaining comfort levels in buildings. for Saving Energy – Grundfos Pumps They deliver and distribute clean drinking water from water treatment plants throughout cities, while at the same time removing wastewater. And, they are highly present within a wide range of industries to Saving Energy – Grundfos Pumps. The world depends on them, but many pumps are also serious energy wasters, leaving behind a significant carbon footprint for Saving Energy – Grundfos Pumps. This is because today’s pumps account for no less than10% of the world’s electricity consumption and because the majority of electricity is still produced using fossil fuels [1].

Pumps and the world’s electricity consumption procent_billede

Today pumps account for no less than 10% of the world’s electricity consumption.

Two third of all pumps use up to 60% too much energy [2].

If every business switched to a high efficiency pump system there could be global savings of 4% of the total electricity consumption- comparable with the residential electricity consumption of 1 billion people.

Tehnik Perawatan Pompa Part 1

Pentingnya Pompa dalam Kehidupan Kita.

Pompa merupakan benda mekanik yang perlu dilakukan perawatan secara berkala, kegiatan ini berguna agar pompa dapat selalu dipakai dalam kondisi yang optimal sehingga menghindari terjadinya resiko kerusakkan pada pompa.

Banyak sekali pengguna pompa yang melupakan kegiatan yang sederhana ini dan baru merasakan dampaknya apabila pompa sudah mengalami masalah sehingga menggangu kegiatan sehari-hari dirumah maupun terganggunya kegiatan produksi di sebuah perusahaan.

Di beberapa Industri, pompa merupakan sarana yang cukup vital, karena bila mengalami gangguan akan berdampak besar pada kegiatan produksinya dan juga menimbulkan resiko kerugian yang tidak sedikit, banyak orang beranggapan kerugian yang terjadi hanya pada biaya perbaikan atau penggantian spare part pompa bilamana terjadi, namun melupakan kerugian atas hilangnya kegiatan produksi barang atau disebut “ Opportunity Loss” contohnya : bila satu hari dalam proses produksi diperlukan air dengan jumlah 1000m3 untuk memproduksi 10000 barang, sehingga bilamana terjadi kerusakkan pompa yang berakibat tidak dapat memproduksi barang sebanyak 10000 barang maka itu yang kita sebut opportunity loss disamping kerugian atas biaya perbaikan tadi.

Oleh Karena Pentingnya kita menjaga kondisi pompa maka diperlukan kegiatan perawatan pompa
