Grundfos TP and TPE vertical in-line volute pumps are used in a variety of applications. The pumps are all single-stage, in-line centrifugal volute pumps with standard motors and mechanical shaft seals. The pumps are of the close-coupled type, i.e. pump and motor are separate units. Consequently, the pumps are less sensitive to impurities in the pumped liquid than similar pumps of the canned rotor type.

Two different models of vertical in-line volute pumps are available. Please note that there are a number of specific product variants available for each model. Detailed information on these variants can be found in Grundfos WebCAPS.

TP pump

This pump model is notable for its high levels of reliability and efficiency.  Quiet, highly-efficient IE3 motors are standard components. All TP pumps are electro-coated to ensure high corrosion resistance.

TPE pump

The main difference between TP and TPE pumps is the motor. TPE motors have a built-in frequency converter, allowing different control methods to be employed. TPE pumps offer benefits with respect to energy savings and increased comfort.

Applications

These vertical in-line volute pumps are used in commercial buildings for air conditioning and heating applications.

The pumps are all single-stage, in-line centrifugal volute pumps with standard motors and mechanical shaft seals. The pumps are of the close-coupled type, i.e. pump and motor are separate units. Consequently, the pumps are less sensitive to impurities in the pumped liquid than similar pumps of the canned rotor type.

Features and benefits

• Optimised hydraulics for high efficiency

• Reduced power consumption

• High-efficiency motors

• TP pumps are fitted with high-efficiency motors
• High-efficiency motors provide reduced energy consumption
• 2-pole and 4-pole TP pumps from 0.75 kW to 375 kW have IE3 motors (By March 2012)

• Top-pull-out design

• Easy dismantling for service

• In-line design

• Unlike end-suction pumps, in-line pumps allow the use of straight pipework, which often results in reductions in installation cost and amount of space occupied

• Hydraulically and mechanically balanced impeller (Series 300 and 400)

• The impeller is hydraulically and mechanically balanced to increase the life of motor bearings and shaft seals

• Pump housing and pump head/motor stool are electro-coated

• Improved corrosion resistance

• TPE, TPED – pumps with built-in frequency converter

• Reduced power consumption

• TPE and TPED motors are based on IE3 motors (except 18.5, 4-pole).

The Grundfos DW pumps are robust, portable submersible pumps with a vertical discharge port. Available with motors from 0.8 to 20 kW, they are designed to handle dewatering at construction sites, at excavation sites, in building drainage and in similar applications where there is a need to pump raw water or/and at high pressure. DW main parts are made of aluminium in order for them to be as light as possible. This factor, in combination with the compact design and the high-pressure capabilities, make DW pumps portable and easy to handle. The semi-open type impeller is made of high-chrome stainless steel (550HB) in order to increase wear resistance. DW.50.08 (only) has a polypropylene motor housing.

Applications

DW pumps are excellent for dewatering and draining jobs. The portable design, wear resistant parts and high pressure capabilities ensure the reliability, sustained performance, user-friendliness and ease of servicing that are necessary in demanding dewatering applications at sites such as:

• Construction sites
• Excavations
• Tunnels
• Steel works
• Fish ponds
• Underground parking drainage Industrial drainage pits.

Features and benefits

• Durability
• Portability
• User-friendliness
• Ease of servicing High pressure capabilities Control options.

Grundfos kembali membuktikan keandalan teknologinya. Lewat kerjasama dengan PDAM Badung Tirta Mangutama, Grundfos menawarkan solusi handal dan hemat biaya bagi sistem distribusi air untuk perusahaan yang telah beroperasi lebih dari 10 windu itu dengan Teknologi Demand Driven Distribution.

Bali, jantung pariwisata Indonesia terus tumbuh,termasuk juga Kabupaten Badung di selatan Bali. Sebagai tempat bernaungnya pantai-pantai dan resor yang terkenal, ribuan hotel dan villa, berbagai kegiatan bisnis serta event dan festival internasional, Badung menjadi tuan rumah bagi rata-rata 2,5 juta pengunjung setiap tahunnya. Itu sebabnya kabupaten ini membutuhkan infrastruktur handal dan berkelanjutan untuk menunjang perekonomian dan industri pariwisata yang terus berkembang.

Satu kebutuhan primer yang harus terjamin pemenuhan kebutuhannya adalah air bersih. Selama ini penyediaan air bersih telah ditangani dengan baik oleh PDAM Tirta Mangutama sejak 1932. PDAM ini sukses meningkatkan kapasitas produksi seiring peningkatan jumlah pelanggan. Sumber air yang dimanfaatkan berasal dari mata air, air tanah, dan air permukaan. Hingga tahun 2012 tercatat jumlah pelanggan mencapai 33.877 yang tersebar dikota dan desa dari petang sampai Nusa Dua. Dengan menggunakan sistem hidrolik konvensional, pompa diInstalasi Pengolahan Air berketinggian 3 meter di atas permukaan laut memompa hingga 3.957m3/hari keseluruh pelanggan.

Sepanjang layanan selama puluhan tahun, PDAM Tirta mangutama telah banyak menghadapi berbagai masalah, diantaranya yakni isu efisiensi. Ada perbedaan cukup besar antara total produksi dan total distribusi air dilapangan. Pada 2012, tercatat sebanyak 21,98% dari air yang dihasilkan tidak pernah sampai kerumah pelanggan. Sebagian besar hal itu disebabkan oleh kebocoran jaringan distribusi. Perusahaan harus tanggap untuk melakukan opti-malisasi sistem produksi dan distribusi air agar tercapai efisiensi melalui inovasi dan teknologi.

Solusi DDD (Demand Driven Distribution) dari Grundfos ditawarkan untuk memenuhi kebutuhan akan efisiensi. Grunfos mampu menyediakan sistem yang terbukti efektif dalam mengurangi kehilangan air akibat kebocoran. Instalasi DDD di PDAM Tirta Mangutama merupakan yang pertama kali dilakukan diwilayah Asia Pasifik.

Tentang alasan memilih solusi ini, Direktur Teknik PDAM I Nyoman Sumarsana ST, MSi menyatakan beliau sangat terkesan dengan hasil penerapan sistem DDD dimana tingkat kehilangan air akibat kebocoran berkurang sebesar 20%, sehingga menghemat air dan mengurangi biaya listrik dan pemeliharaan. “Grundfos telah menjawab masalah kebocoran dengan sistem Demand Driven Ditribution. Sistem ini merupakan terobosan teknologi dalam distribusi air.

Grundfos menginstalasi sistem DDD dalam sistem pengolahan dan distribusi PDAM Tirta Mangutama. Selain Itu, untuk mendukung monitor terhadap operasi aplikasi DDD, Grundfos melakukan sosialisasi terhadap seluruh karyawan dalam bentuk pelatihan-pelatihan dan seminar.

Sesuai dengan namanya, Demand Driven Distribution adalah sistem dimana air didistribusikan kerumah-rumah pelanggan dengan tekanan yang diatur sesuai permintaan, bukan berdasarkan tekanan yang disediakan. Sistem ini berlandaskan pada konsep baru, yaitu dengan tekanan yang lebih rendah air masih bisa dialirkan ke setiap rumah. DDD diterapkan dengan manajemen tekanan, yang memungkinkan untuk mengontrol tekanan dalam sistem distribusi serta menyesuaikannya untuk memenuhi permintaan yang sesungguhnya. Sistem distribusi air yang kurang efisiensi tidak hanya membuang air tetapi juga daya yang diperlukan. Selain itu juga karena tekanan yang selalu konstan baik pada saat konsumsi tinggi maupun rendah, menyebabkan pipa-pipa tidak awet. Akibatnya keborosan juga terjadi pada perawatan  dan perbaikan, belum lagi daya listrik yang terpakai.

Dengan tekanan lebih rendah dalam sistem DDD, lebih sedikit daya listrik yang dikonsumsi dalam distribusi air, umur pipa menjadi lebih panjang, dan lebih sedikit diperlukan pemeliharaan serta perbaikan dalam jaringan pipa. Jadi, selain menghemat air, DDD juga membantu menurunkan konsumsi energi dan biaya pemeliharaan

Didukung layananan purna jual yang memadai, kerja sama ini akan terus memberi manfaat dan keuntungan bagi masyarakat Kabupaten Badung saat ini dan mendatang. Grundfos terus mengembangkan sistem ini sebagai sebuah solusi berkelanjutan yang hemat biaya dan ramah lingkungan bagi kehidupan masyarakat di Kabupaten Badung. ( Grundfos Pump News)
