At High Pressure Tech, we offer a variety of Maximator air driven pumps to meet specific application requirements. Our liquid pump category consists of more than 20 different types of pumps, and pump series. Given below are some of the popular products that we offer.
PP Series: The PP Series pumps are lightweight, and feature a rugged construction of anodized aluminum bodies. These air driven liquid pumps are capable of increasing pressures from 60 to 58,000 psi.
PPO Series: These pumps are specifically designed for applications comprising oil, or a combination of oil and water. The PPO pumps are known for their immense power and portability. They are also versatile, providing 8 pressure ratio options.
S Series: S Series pumps are designed for oil and oil-water applications. They are particularly useful for static and mobile applications. Available in five pressure ratios, these pumps provide pressures ranging from 105 to 14,500 PSI.
S-D Series: Pumps in this series are the double acting version of the S Series products. The S-D Series pneumatic driven pumps can also be used in static and mobile applications. However, they provide five pressure ratio options, ranging from 105 to 14,500 PSI.
GX Series: The GX Series pumps are high flow products, and provide pressures ranging from 540 to 14,500 PSI. They are the perfect choice for offshore applications, or where pump installation needs to be durable.
L Series: These liquid pumps are capable of providing pressures between 165 and 60,000 PSI. Maximator L Series pumps are constructed with stainless steel bodies. They can be provided in single and double acting models.
L-D Series: Maximator L-D series are double-acting pumps are designed for water or oil services. The L-D pumps dual inlet and dual outlet ports are deliver 50% more flow rate than the L series pumps with less pulsation. These pumps are available in various pressure ratios from 150 to 38,425 PSI.
LSF Series: Designed for chemical applications, the LSF Series pumps provide pressures ranging from 165 to 23,200 PSI. These air driven high pressure liquid pumps are available in single acting models, and can be provided with either a single or a double air drive head.
PPSF Series: Similar to the LSF series, the PPSF pumps are designed to assist chemical applications at pressures from 60 to 14,500 PSI. The single acting pumps are provided with single and double air drive heads. A distance piece is used to separate the air drive and liquid sections.
PP-HL Series: This series comprises lightweight, and hand-operated pumps. They provide pressures up to 31,900 PSI. The PP-HL pumps have the capability to generate pressure even when there is no pressure available. They are ideal for pressure gauges and transducers.
GPD Series: The GPD Series liquid pumps are designed for applications, which require fast liquid filling. These double acting pumps with single heads provide high discharge flows at high pressures. GPD pumps can handle water, chemicals, and hydraulic oils.
Construction and Operations
The operation of high pressure liquid pumps is based on the principle of an oscillating pressure intensifier. In simple terms, the principle states that pumping can continue even if the pressure reduces. The pumps function using compressed air ranging from 1 to 10 bar. This allows the pump to continue its operation despite any pressure drops.
The construction of Maximator pumps is designed to support the oscillating pressure principle. They feature the following components:
- Drive piston
- Suction chamber
- Air piston joint
- Diameter plunger
- Inlet check valve
- Outlet check valve
The air piston joint is connected to the small diameter plunger. The pressure ratio is the key to determining the maximum outlet pressure. Higher outlet pressures can be gained by simply increasing the pressure ratios.
The pumps are self-priming, and generally do not require the use of airline lubricator. The liquid flows into the suction chamber due to the upstroke of the drive piston. This suction effect causes the inlet check valve to open, while and the outlet check valve is closed. Down-stroke generates the required pressure for an application. The generated pressure causes the inlet check valve to close, and the outlet check valve to open. The pressure is then transferred to the application equipment.
Maximator pneumatic liquid pumps consist of automatic cycles. The cycles slow down when there is a build-up of pressure. Once the output pressure forces are equalized, the pump stops automatically. The pump restarts if there is an increase in the air drive pressure, or a slight drop in.
Maximator high pressure pumps can provide a variety of benefits to technical applications in various industries.
- The pressure can be regulated by using one of two components - manual pressure control units, or pneumatically triggered valves.
- The pneumatic liquid pumps are extremely appropriate for application in explosion-proof areas.
- Substitution of leakages by automatic additional delivery of liquid from the pump
- The pump does not consume excess energy even when it is maintaining the requisite pressure for long periods of time.
- No heat loss takes place during the pressure holding stage.
- The high pressure liquid pumps provide ease of installation and quiet operation.
- The pump is self-contained. The product only requires connections for the suction, pressure lines, and air supply.
Maximator high efficiency pumps are ideal for a broad variety of oil, water and chemical applications.Chemical and Offshore Applications

Tips and Warning
The following tips and warnings can help ensure durable operation and performance of Maximator air driven liquid pumps.
- The pump’s outlet pressure can be set easily via an air regulator.
- The model numbers of each pumps reflects the nominal pressure ratios, while the technical data indicates the exact ratios.
- In an application, the minimum liquid pressure can be calculated by multiplying the pressure ratio with the available shop air pressure.
- The performance of the pneumatic liquid pump can be effected by a number of conditions. These include dirty filters, deficient inlet sizes, and freezing of the pilot valves.
