GDL型立式多級(jí)管道泵采用葉輪多級(jí)對(duì)稱布置，以水力平衡消除軸向力，提高了泵的運(yùn)行平穩(wěn)性，軸封選用耐磨機(jī)械密封，泵進(jìn)出口在下方成一字形，安裝條件優(yōu)于DL泵，適合于流量小、揚(yáng)程高、多臺(tái)泵并聯(lián)使用.
GDL型立式多級(jí)管道泵具有外形美觀、無泄漏、性能穩(wěn)定、占地面積小、安裝方便、使用壽命長(zhǎng)等優(yōu)點(diǎn)。
，適用于高壓運(yùn)行系統(tǒng)中冷熱水的循環(huán)和增壓、高層建筑多臺(tái)泵并聯(lián)供水、鍋爐給水和冷卻水系統(tǒng)及各種沖洗水的輸送。
介質(zhì)溫度：-15攝氏度--120攝氏度；流量范圍為1.1--192m3/h；揚(yáng)程范圍為22--230m；配套功率范圍為1.1--132kw，口徑范圍為φ25--φ150mm.
