Haskel Liquefied Gas Pumps

Haskel’s range of Air Driven Liquefied Gas Pumps offers complete flexibility for your liquefied gas pumping needs. A wide range of sizes provide flow rates as high as 25 lbs/min and develops output pressures up to 10,000 psi.
These features, coupled with the ability to boost most common liquefied gases, make Haskel Air Driven Liquefied Gas Pumps the preferred solution for a wide cross section of applications.
The key design elements incorporated in this range are based on the Haskel technology that has been successfully utilized for over thirty years. This technology has been combined with industry specifications in order to provide optimum liquefied gas pump performance.
This brochure details the standard range of Haskel Air Driven Liquefied Gas Pumps. Additionally, fully engineered, custom designed systems are available from Haskel, the quality high pressure technology company.

Features and Benefits

• Comprehensive Range
Provides solutions for applications requiring low to high pressure ratios and a wide range of performance.
• Cooling
No need for feed pumps or expensive cooling in most applications. Reduces heat transfer from drive section to pumping section.
• Reliability
Simple, efficient design based on over 50 years of experience in liquid/gas applications. Easy service and maintenance.
• Full Insulation
Reduces heat transfer from drive section to pump section.
• Efficient
Transfers and compresses large volumes of liquefied gas at high supply and discharge pressures. Minimizes unswept volume and improves tolerance to flashing. Improves pumping efficiency and promotes self flushing of vapor pockets.
• Priming
Ability to stop/start without bypass circuit and rapid reprime capability, without losing downstream pressure.
• Economical
Ability to pump in liquefied condition provides substantial economic benefits over alternative “gas” transfer.
System Considerations When Pumping CO2

CO2 is a liquefied gas and needs specific system considerations in order to be pumped efficiently as a liquid. Typically CO2 is delivered as a liquid at 200 psig @ -20 deg. F or 300 psig @ 0 deg. F.
Haskel CO2 pumps will accept inlet pressures up to the maximum rated outlet pressure of pump. Cooling jackets are designed for 800 psig max. Haskel does not recommend routing outlet CO2 from the pump through the cooling jacket.
All Haskel ALG series pumps are designed to increase tolerance to “flashing” inside the pump. For maximum reliability, it is recommended that the inlet piping be designed with a minimum of 1 meter (H2O) positive NPSHA at pump inlet. Line sizes should be at least as large as the inlet to the pump. It should not be assumed that if in-plant CO2 is available at 300 psig that the piping is sized properly for temperature insulation and pressure drop.
Caution should also be taken to maintain proper temperatures of CO2 from the tank supply to the pump inlet. Proper insulation of the inlet pipe and pump body is mandatory for good efficient pump rates. Please consult factory if uncertain of the piping design.
Haskel ALG series single acting pumps use a 3-way cycling spool allowing the pump piston to be returned by the positive pressure of inlet CO2. This eliminates “suction” inside the pump cavity. This allows the pump to run at maximum speed while minimizing any tendency to “flash” to a gas state, which would reduce pumping efficiencies.
In order to avoid excessive heating effects, Haskel recommends sizing single acting pumps (ALG-8, ALG-15, ALG-32, ALG-60, ALG-122) to limit the maximum cycle rate to 40 cpm. Double acting models should be limited to 30 cpm max.

There are two methods of cooling the pump body. One method is use of a “chiller” with a water glycol solution. The chiller should be designed with a minimum of 3 gpm and adequate BTU/hour rating.
The other method of cooling is to route the “inlet CO2” through the cooling jacket of the pump. Using CO2 for the coolant requires a recirculation pump to feed the Haskel ALG pump and the cooling circuit. Please consult the factory for recommendations. The
recirculation pump should provide approximately 40 - 70 psig lift for transferring the CO2 through the jackets and back to tank. This pump should be located as close to the CO2 tank as possible with care taken to maintain the line sizes and insulation. Again, please consult the factory if uncertain of circuitry necessary.

Typical Applications

In recent years, there has been an increased demand for liquefied gases within many industries. Some liquefied gases such as Carbon Dioxide (CO2) are now commonly used in applications that previously utilized halocarbons such as Halon, Freon, etc.
The ALG Series described in this catalog is utilized throughout many industries for such applications as supercritical (dense phase) extraction, plastic and foam manufacture and fire protection.
In addition to supplying bare pumps, Haskel also specializes in the design and manufacture of custom system solutions.

INJECTION RATE CONTROL DEVICE Haskel IRCD Injection Rate Control Devices
The Haskel IRCD is a unique and revolutionary system for the multi-point injection of chemicals into oil and gas production systems. The IRCD can be supplied as individual units or in a panel configuration, which can be installed adjacent to the point of injection. It only requires one high pressure feed line from either an air or electric-driven chemical injection pump, regardless of the number of injection points the system has.
The NEW Compact Haskel IRCD
Uses all ceramic and PEEK™ metering and regulating parts to overcome many of the problems usually associated with flow control valves, such as chemical adhesion. This technical advance together with new geometry metering valves gives even longer life and fewer blockages, all combined in one compact valve design.
This revolutionary design can handle flow rates from as low as .5L/hr up to 320 L/hr (85 USGPH) with injection pressures up to 15,000 psig and flow turndown of up to 50:1 (flows up to 6,000 L/hr can be achieved with larger models).
