KRAL pumps with magnetic coupling are hermetically tight, the pump station as well as the site itself stays clean. As magnetic couplings work without wear and maintenance-free, the life cycle costs are favourable comparative to conventional sealing systems.
Please consider that we are a manufacturer of high quality displacement pumps and flowmeters for liquids. The products (pumps with magnetic couplings, high pressure flowmeters and flowmeters – chemically resistant) mentioned on this portal are only part of our product range.

The new generation Series K has been thoroughly reengineered. As the most sold universal pump series K offers a number of benefits.
The pump prevents the accumulation of residue forming fluids by locating the leakage hole before the ball bearing. Secondly, KRAL offers the advanced quality of SiC mechanical seals, which contains graphite, as a solid lubricant to reduce the coefficient of friction in dry running conditions. The O rings with high fluorine content are suitable for higher temperatures and are chemically stable. The Series K offers innovative seal concepts. A proven selection of radial rotary shaft seals, mechanical seals and a hermetically sealed magnetic coupling are available as standard. A robust and compact design rounds off the profile.
Your advantages:
- No coupling damage through well placed leakage hole.
- Safety reserve in dry running.
- Low maintenance operation.

No more problems with mechanical seals:
Compared to mechanical seals the magnetic coupling is hermetically tight.
Magnetic couplings can be used up to 250°C. A mechanical seal can only be used up to 150°C.
More benefits:
Beware engine failures.
Reduced lifecycle-costs – long life cycle.
The hermetically sealed magnetic coupling prevents pump failures, caused by fuel residues.
No required lubrication as at mechanical seals. Dry running is not possible.
Leakage free and clean. Benefits for all, which commit to Greenship Technology.
Guarantee on-board safety. (SOLAS – “Safe of Life at Sea”)
Overload protection.
Maintenance-free.

The Marine Screw spindle pumps are positive displacement rotary type pumps. The main working parts of the pumps are three helical spindles and the pump housing. The helical spindles or screws can be compared with a gear having a very long, curved tooth, or with a piston pump with an indefinite numbers of pistons.
Technical data:
CapacityUp to 3300 l/min
HeadUp to 80 bar
Viscosity12 - 800 cst
TemperatureCast Iron up to 180°C
Steel case up to 260°C
Advantages:
The pumped medium is transported axially without turbulence and mixing, thus making possible pumping of very viscous fluids without foaming. The working volume of the pump remains unchanged and moves from the suction to the discharge chamber, ensuring in this way a continuous rate of discharge. Noiseless operation, long service life and high overall efficiency.

Positive displacement pump with three profiled spindles that realize thei movement into the speical bushing.Built in overflow safety valve with a purpose-protection against too high pressure. It is characterized with quite and noiseless work, flow without pulsation and high efficiency.
Available materials: Cast Iron( Gray,Ductile), cast steel, SS(AISI 304, 316), Duplex SS, Super duplex ss, bronze , Al, other on request.
Main advantages compared to other volumetric pumps:
- Pumps are made in horizontal and vertical accomplishment with adequate fitting flanges in horizontal or vertical position;
- Working spindles are totally hydraulically disburdened of axial forces. Fluid is moving axially without turbulence and mixing which enables pumping of a lot of viscous fluids without making foam;
- Working volume remains constant and moves from suction to the discharhe chamber,with what continuous flow can be accomplished;
- Overflow of fluid in case of overburden is made in the suction chamber of the pump or in the tank;
-Noiseless work, long service lifetime and high coefficient of utilization.
Capacity Up to 300 m3/h
Head Up to 80 bar
Viscosity 12 - 800 cst
Temperature Cast Iron up to 180°C
Steel case Up to 260°C

| The Triro pump is of the positive displacement axial flow screw type with only three moving parts - a power rotor and two idler rotors. These three rotors (hence the brand name TRIRO) have accurately machined intermeshing threads which enfold the liquid being pumped and act as seals in relation to each other and to the pump body or sleeve in which they rotate. |

The Twinro 2 screw pump is a heavy duty, fixed flow transfer unit. It is available in either Iron, Steel or Stainless Steel constructions to suit a variety of duties. The design of the screwset means the screws intermesh without metalic contact, making the pump suitable for non-lubricating duties. The pump is available in two configurations :
Outboard bearing pumps suitable for non-lubricating liquids, such as Petroleum Liquids, Palm Oils, Fatty Acids and Water Emulsions.
Inboard bearing pumps suitable for lubricating liquids, such as Lube Oils, and clean Fuel Oils. |

This unit is able to fulfil the highest requirements for a wide range of applications. By entering the load and output into your customer system, the air supply system automatically and directly adapts to the given requirements. The frequency-controlled drive unit offers a wide control range with optimised demand matching. In addition to energy savings and higher efficiency, this also results in lower maintenance requirements. The non-contact, oil-free screw unit ensures high air flows with low pulsation and lends itself to "master/slave" operation. Integrated accessories include a non-return valve, intake filter, sound absorbers and ventilation/bleed system. An air blast cooler is also available.
