安裝靈活，運(yùn)行噪音低

獨(dú)特的入口配置允許在頂部和側(cè)面布置入口，以適應(yīng)低凈空安裝。底部和側(cè)面的排放連接提供了解決安裝空間限制的靈活性。大型檢查口可以方便地進(jìn)入泵內(nèi)進(jìn)行檢查和維護(hù)。

P2620泵在運(yùn)行期間非常安靜。即使是更大型的泵，聲級(jí)記錄也只有72至85 dB(A)（距離聲源3.3英尺（1米）處測(cè)量）。

專(zhuān)為要求苛刻的環(huán)境而設(shè)計(jì)

設(shè)計(jì)為在造紙、電力、采礦、制糖和化學(xué)加工業(yè)等苛刻環(huán)境中運(yùn)行，這些泵以低運(yùn)營(yíng)成本提供耐用性和可行性。P2620真空泵泵體上的標(biāo)準(zhǔn)聚異戊二烯襯里可抵抗腐蝕性工藝氣體和液體，從而提供出色的耐腐蝕性。與同等無(wú)襯層泵相比，聚異戊二烯襯里消耗的能量也更少。

Liquid Ring Vacuum Pump

Large Capacity, P2620

Capacity 14,000 to 21,800 ACFM (23,800 to 37,000 m3/h)

The NASH P2620 liquid ring vacuum pump model allows efficient operation over the entire vacuum range without the need to change the pump's internals. With the largest capacity in our portfolio, ranging from 14,000 to 21,800 ACFM (23,800 to 37,000 m3/h), the P2620 is designed to operate in demanding environments such as paper, power, mining, and chemical process industries.

Description

Split Vacuum Capability

When a NASH P2620 vacuum pump is equipped with a center shroud, split vacuum operation up to 10 inHg (340 millibars) differential can be achieved. The advantage of this is significant, allowing usage of fewer vacuum pumps - which saves space and installation costs.

Flexible Installation & Quiet Operation

The unique inlet configuration allows for both top and side inlet arrangements to accommodate low headroom installations. Bottom and side discharge connections offer flexibility to address installation space constraints. Large inspection ports allow easy access to pump internals for inspection and maintenance.

P2620 pumps are amazingly quiet during operation. Sound levels of 72 to 85 dB(A) (measured at a distance of 3.3 ft (1 meter) from the source) have been recorded for even the largest of the pump models.

Designed To Operate In Demanding Environments

Designed to operate in demanding environments like the paper, power, mining, sugar, and chemical process industries, these pumps offer durability and reliability at a low cost of operation. The standard polyisoprene lining on the P2620 vacuum pump body resists aggressive process gases and liquids to provide exceptional corrosion resistance. The polyisoprene lining also consumes less energy than the equivalent unlined pump.
