SIHI LIQUID RING PUMP LPH SERIES PT PETRO TEKNIK PERSADA PUMPThe SIHI "LPH" series liquid ring vacuum pumps are reliable pumps that can be used in a variety of applications. The vacuum pumps have one moving part, the impeller and shaft assembly, and no internal metal to metal contact. The "LPH" series are available in a single stage (low to medium vacuum) and two stage (medium to high vacuum) configurations for optimum performance. These pumps are available in a wide range capacities and materials of construction to meet your requirements. The pumps can use a variety of liquids to seal the internal clearances. Let us help you decide how the "LPH" series vacuum pumps can best be applied to your application.Features: LPH• Vacuums to 29" Hg. and greater in single and two stage design• Operational safety• Entrained liquid handling• Long economical life• Low vibration & noise level• Low starting torque• Construction flexibilityTechnical Data:Capacity: ½ to 6000 ACFMVacuum: to 29" HgMaterial: Cast & Ductile irons, Bronzes,Stainless Steels, Hastelloys, Titanium & other alloys.Pompa Air

SIHI LIQUID RING PUMP LEH SERIES PT PETRO TEKNIK PERSADA PUMP The North American made LEH series, offer efficient single stage operation through the entire vacuum range. The vacuum pump has the capability of running up to 29" Hg vacuum. These pumps use the liquid ring principle to ensure maximum safety in compression of hazardous mixtures. Reliability is ensured through the use of only one rotating assembly with no internal metal to metal contact.The interior variable port design increases efficiency throughout the operating range. Wear-resistant ball check design increases reliability and lowers maintenance cost.Features: LEH• Variable connection positions• Near isothermal compression• Anti-cavitation• Internal liquid recirculation• Process safetyTechnical Data:Capacity: 220 to 540 ACFMVacuum: to 29" Hg

SIHI LIQUID RING PUMP LEM SERIES PT PETRO TEKNIK PERSADA PUMPThe LEM close coupled liquid ring vacuum pump series offers the ultimate in multi service robust simplicity manufactured in North America. This series of pumps feature cavitation protection, single North American mechanical seal, single casing drain, continuous solids purge connection, ultimate vacuum approaching 29" Hg. (25 Torr), and minimum space requirements.LEM vacuum pumps are close coupled to North American motors of NEMA design. Motors are supplied in compliance with ‘UL’ and ‘CSA’ requirements. These vacuum pumps require no base-plate for mounting, no coupling, coupling guard, or on-site alignment of pump and motor. Perfect for use in OEM equipment.LEM vacuum pumps are capable of handling many vapors, and gases using service liquids compatible with the metal parts and elastomers of the pumps and mechanical seal. Small quantities of liquid carryover and nonabrasive solids can also be handled.Features:• Standard close-coupled design• Simplified construction• 100% North American made• Available in three standard metallurgies• Compact• Quiet• Process safetyTechnical Data: Capacity: 7 ACFM to 160 ACFMVacuum: to 29" Hg.Temperature: 212°F (100°C)Materials: High grade cast iron with bronze impeller, cast iron with 316 SS impeller, and all 316 stainless steel wetted parts for difficult applications

SIHI LIQUID RING PUMP LEME SIHIEXTRUVAC SERIES PT PETRO TEKNIK PERSADA PUMPThe SIHIextruvac is applied to the handling and exhausting of dry and humid gases. These pumps are applied in all fields where a pressure of 100 to 900 mbar must be created by robust vacuum pumps. The SIHIextruvac (or LEME) is specially designed to handle additional water that is exhaust through the suction inlet.During operation the pump must continuously be supplied with service liquid, normally water, in order to eliminate the heat resulting from the gas compression and to replenish the liquid ring, because part of the liquid is leaving the pump together with the gas. It is possible to reuse the service liquid. The pumps are equipped with a device by which the contaminated service liquid can continuously be drained during operation (dirt drain), if necessary.SIHIextruvac Features:non-polluting due to nearly isothermal compressionlow noise and nearly free from vibrationoil-free, as no lubrication in the working chambershaft not contact with the mediumhandling of nearly all gases and vapoursprotection against cavitation as standardable to handle water carry overincorporated central drainwide choice of material for application versatilityincorporated dirt draineasy maintenance and reliable operationno metallic contact of the rotating partsTechnical Data:Capacity: 70 ACFM to 100 ACFMVacuum: to 27" Hg.Temperature: 212°F (100°C)Materials: High grade cast iron (ASTM A48 CL 30) with Red Brass impeller, stainless steel intermediate, Stainless Steel/Teflon Valve Assembly, and Carbon Steel/Carbon/Buna Elastomers Mechanical Seal

KEH Liquid Ring Compressor PT PETRO TEKNIK PERSADA PUMPThe KEH series, offers a greater pressure range. Capable of operating with a negative inlet pressure (vacuum) and a positive discharge pressure. These pumps use the liquid ring principle to ensure maximum safety in compression mixtures.The Principle of the liquid ring pump is dependent upon a continuous supply of cool, clean service liquid, normally water, which enters the pump at the initial stages and is discharged from the final stage together with the compressed gas.Features: KEH• Pressure range flexibility• Operational safety• Reliable operation• Construction simplicity• Robust construction• External bearing arrangement• Handles entrained liquid and vapor handling• Low vibration and noiseTechnical Data:Capacity: up to 500 SCFMPressure: up to 35 PSIGMaterial:Cast iron with bronze or stainless steel impellerNote: please consult Factory for applications exceeding these ranges, or requiring a negative inlet pressure.Accessories:SIHI Pumps can provide service liquid arrangements in completely piped, assembled and tested factory packages
