LY VS4/VS5
VERTICAL CHEMICAL PROCESS
Pompa LY VS4/VS5 Vertical Chemical Process adalah pompa
sentrifugal vertikal tipe long shaft/submerged yang dirancang
untuk kebutuhan industri kimia, petrokimia, refinery,
pengolahan limbah, dan berbagai proses fluida industri.
Pompa ini memiliki motor di bagian atas, shaft vertikal
panjang, serta impeller yang bekerja di dalam cairan sehingga
cocok digunakan pada sump, pit, tangki proses, atau bak
penampungan. Dengan konstruksi vertikal, pompa ini hemat
area instalasi, mampu menangani cairan bersih maupun
cairan terkontaminasi ringan, serta dapat menggunakan
material tahan korosi sesuai karakter fluida.
