P Type Site Trolley (Diesel)

The diesel site trolley is an ideal machine for industrial cleaning applications on sites where the equipment needs to be mobile but not required on the highway. The purpose built site trolleys are available in different sizes with performances up to 6000 psi (415 bar) to suit each customer’s requirements. These can be towed around the customer site by fork lift trucks or similar.

Fitted with the unique Harben® P Type pump featuring multi-cylinder design ensuring pulsation free operation, tubular diaphragm pumping chambers eliminating piston seals, all moving mechanical parts immersed in hydraulic oil bath – moving parts in contact with the pumped media are limited to the diaphragm, inlet and delivery valves. The nature of the pumps design allows the use of “dirty” water, filtered to only 150 microns, whereas conventional plunger pumps need filtering to 50 microns, and gives the ability to run dry without damage.
