The MAXIMATOR pneumatic drive concept offers a number of advantages:
- Pressure regulation using manual pressure regulators or pneumatically controlled valves.
- Pneumatic actuators, i.e. The pumps are especially suitable for use in explosion-proof areas.
- Stopping the pump when the specified limit pressure is reached
- Replacing leaks with automatic additional fluid supply from the pump
- No energy consumption for long periods of pressure maintenance
- No heat loss during the pressure maintenance phase
- Easy installation and trouble-free operation of the units. Only connections to the air supply and suction and pressure lines are required.
- Operationally reliable, easy to install and unpretentious to maintain units, silent in operation.
MAXIMATOR pumps are available in 5 sizes: M, S, G, GX, DPD. Sizes vary depending on their suitability for different fluids handled, speeds and flows and maximum permissible operating pressure. To select and order the hydraulic pump that is best suited for your application, the following parameters must be observed:
1. Working environment
The type of fluid is important when selecting a MAXIMATOR pump, so the wetted material and seal composition are determined by the specific fluid. MAXIMATOR pumps are available for a variety of applications. The two most important standard pumps Designed for use with oil or water .
2. Available air pressure
MAXIMATOR pumps are designed for a maximum pneumatic drive pressure pL = 1 to 10 bar .
3. Required hydraulic outlet pressure and flow capacity.
The outlet pressure indicated in the technical tables of the pumps is based on the maximum pressure of the pneumatic drive pL = 10 bar. The actual outlet pressure in your particular case is determined by the air actuator pressure multiplied by the pressure coefficient, pL * i.
High efficiency MAXIMATOR pumps are ideal for a wide range of oil, water and chemical applications. MAXIMATOR pumps have a pneumatic drive and drive air pressure from 1 to 10 bar. In essence, the operating principle is similar to a piston amplifier, in which the control of the piston in the final position is controlled by a pilot-controlled 4/2-way valve.
MAXIMATOR pumps have a large air piston connected to a smaller diameter plunger. The pressure coefficient is the difference between these two areas and is a method for determining the maximum outlet pressure. Higher pressures are achieved by using higher pressure ratios. MAXIMATOR model numbers reflect the pumps’ pressure ratings, and technical data indicates the exact ratios. Outlet pressure can be easily adjusted using a simple air regulator. By multiplying the pressure rating by the available air pressure in the shop, the rated fluid pressure can be calculated.
MAXIMATOR pumps are self-priming. There is generally no need to use an air line lubricator. The pumped liquid enters the suction chamber as the drive piston moves upward. This suction effect causes the inlet check valve to open and the outlet check valve to close. The downstroke creates pressure on the liquid side. The inlet check valve is closed and the outlet check valve is opened by the pressure generated.
MAXIMATOR liquid pumps operate automatically. As the pressure increases, the number of cycles slows down. The pump stops automatically when the output pressure forces become equal. The pump restarts when there is a slight drop in outlet pressure or an increase in air drive pressure. Pump performance can be affected by a number of conditions, such as frozen muffler or pilot valves (caused by moisture in the air lines), improperly sized air intake lines, and dirty filters.
