Specification

Piston-vacuum pump is universal unit used to reduce soil water level, adapted to all type of soil. The construction is simple and strong, assure high durability and very high efficiency.

Depending on type of soil, pump operates with 40 to 100 needle-filters and with 40 to 300 metres of suck lines. Pump creates vacuum up to 9,6 metre and may suck in: air, water, mixture of water with air.

Pump PTP 65 is produced in two versions:

• PTP 65E type - with electric engine drive
• PTP 65S type - with fuel engine drive

Standard pump is mounted on the stationary sleigh, but there is a possibility to mount it on the mobil chassis.

Advantages of the pump

• sucking of water, air and water-air mixture
• sucking from a depth of 9,6m
• pulsating operation to prevent weelpoints clogging [picture]
• extremely high efficiency
• high reliability
• simple and strong construction
• minimal maintenance
