Johor,Johor Bahru (JB),Penang,Selangor,Kuala Lumpur (KL),Perak,Taman Austin Perdana,Sarawak,Kuching,Sibu,Bayan Lepas,Singapore,Jeram,Sitiawan NHS-35 Diffusions Pumps - Agilent Technologies from ELSO Technologies Sdn Bhd

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.

Five-stage stainless steel fractionating jet purifies fluid.
High tolerable forepressure.
Full thermal protection.
Fluid-level sight glass provides quick indication of pump fluid status at all times.
Foreline baffle prevents fluid loss to backing system.
Optional halo baffle cold cap reduces backstreaming without adding height.
Standard gauge port (NW-25) below inlet flange included.
Optional quick cool coil.
