Модель: HS-20 Diffusion Pump
Наличие: Есть в наличии

Available in 2 in. and 16 in. through 35 in. sizes, the low-cost HS-series pumps provide high speed, low ultimate pressure, high throughput, high tolerable forepressure, and low backstreaming. The HS-Series diffusion pumps come with full thermal protection and optional quick-cool coils. The 16 in. through 35 in. pumps come with sight glass/fill and drain assemblies, and are available with ASA or ISO flanges.

Features

  • Five-stage fractionating jet purifies pumping fluid and assures low base pressure.

  • High tolerable forepressure.

  • Full thermal protection.

  • Fluid-level sight glass provides quick indication of pump fluid status at all times.

  • Fill and drain assembly for pump oil.

  • Standard gauge port (NW-25) below inlet flange included.

  • Foreline baffle prevents loss of fluid into backing pump system.

  • Optional halo baffle reduces backstreaming without adding height.
