The angle of the propeller/impeller blades can be adjusted by hand. This makes it possible to adapt the unit to use in different conditions.

Motor

Dry motors (T motors) give off their heat directly to the surrounding fluid via the housing components and can be used in immersed state for permanent operation.

A sealing chamber protects the motor from fluid ingress. It can be accessed from the outside and can be monitored with an optional sealing chamber electrode.

All filling fluids used are potentially biodegradable and environmentally safe.

The cable inlet of the T motors is longitudinally watertight. Cable lengths can be individually configured.

Pompa Submersible atau Electric Submersible Pump (ESP)

All About Submersible Pumps & Electric Submersible Pumps

Pompa submersible atau Electric Submersible Pump (ESP) adalah sebuah pompa yang dirancang khusus, di mana motor dan komponen-komponen lainnya tertutup rapat, karena pada penggunaannya nanti seluruh permukaan pompa ini akan terendam ke dalam cairan. Pada umumnya pompa yang sering kita jumpai berada di atas cairan dan menyedot cairan sebagaimana pompa jet (Jet Pump). Berbeda halnya dengan pompa ini. Pompa ini diletakkan di dalam cairan dan mendorong cairan melalui pipa-pipa salurannya. Pompa ini lebih efisien dibandingkan pompa jet. Penggunaan teknologi pompa ini banyak dijumpai di dalam dunia industri.

Prinsip Kerja Pompa

 

Pompa-pompa submersible yang digunakan dalam instalasi Electric Submersible Pump (ESP) adalah pompa sentrifugal multistage yang dioperasikan dalam posisi vertical. Meskipun dari tahun ke tahun kontruksi pompa submersible semakin berkembang dan memiliki banyak fitur, namun sebenarnya pompa submersible memiliki prinsip kerja dasar yang sama. Cairan diputar oleh impeller dengan kecepatan rotasi yang tinggi sehingga mengalami gaya sentrifugal, kemudian cairan tersebut kehilangan energi kinetik di dalam diffuser di mana konversi energi kinetik menjadi energi tekanan berlangsung.

Skema Umum Pompa Submersible

Penggunaan Pompa Submersible

Pompa submersible banyak ditemukan dalam dunia industri. Pompa ini biasanya digunakan untuk drainase, industri pompa umum dan pemompaan lumpur. Pompa ini juga banyak digunakan dalam filter kolam. Jenis pompa submersible bertingkat biasanya digunakan pada lubang bor dan digunakan untuk abstraksi sumur air dan sumur minyak. Pemanfaatan pompa submersible yang lain yaitu digunakan pada instalasi pengolahan limbah, penanganan air laut, pemompaan air tanah, pemadam kebakaran (karena kabel tahan api), pengeboran sumur bor dan air, pengeboran lepas pantai, lift buatan, dewatering tambang dan sistem irigasi.

Kelebihan Jenis Pompa Submersible

Dari beberapa macam dan jenis-jenis pompa air, jenis pompa submersible didesain dan dirancang khusus dan berbeda dengan jenis pompa lainnya. Cara peletakkan pompa submersible yang di dalam air ternyata memiliki beberapa efek menguntungkan. Beberapa kelebihan pompa submersible yaitu:
  1. Secara tata letak, penggunaan pompa submersible lebih praktis karena penempatannya berada di dalam sumur
  2. Tidak bising karena berada di dalam air maka suara bising pompa diredam oleh cairan
  3. Pompa tidak mudah panas. Cairan (air) memiliki kecenderungan memiliki suhu yang relatif dingin dan stabil. Karena keberadaan pompa di dalam air, maka pompa submersible tidak mudah panas
  4. Sistem pompa submersible tidak menggunakan shaft penggerak yang panjang dan bearing, jadi permasalahan yang biasa terjadi pada pompa permukaan (Jet Pump) seperti bearing dan shaft yang aus, tidak terjadi pada pompa submersible.
