DESCRIPTION

The KT-Series pumps covered herein have an oil 

circulating pump to provide adequate lubrication at 

all pressures including atmosphere. The vacuum 

pump has three cams and pistons pumping in parallel, 

driven by a common shaft. The cams are positioned 

on the shaft so as to dynamically balance moving 

parts. This balancing technique applied to the Rotary 

Piston Principle was developed by Kinney Vacuum and 

virtually eliminates vibration.

Figure 1 shows a cross section of the pump with the 

pistons being driven by the cams and revolving within 

the cylinder.

Gas is drawn into the pump through a common inlet, 

channeled to the three piston slides and into the space 

behind the pistons as they rotate. 

The gas ahead of the pistons is compressed and forced 

out the discharge valves. As the gas is forced through the pump, sealing oil is mixed with the discharged gas and the discharged 

mixture is channeled into the separator, which is located in the reservoir, and there the gas is separated from the oil.

Sealing and lubricating oil is provided by the oil pump which is mounted on the non-drive head and driven by direct coupling to 

the vacuum pump drive shaft. The oil pump provides forced feed oil circulation at all operating pressures including atmosphere. All 

models have a channeled drive shaft with an opening at each cam to distribute oil through the pump.

Oil is taken from the reservoir at a point some distance above the reservoir bottom. This provides an area for impurities to collect 

for draining.

INSTALLATION

INSTALL VIBRASPRINGS

KT-840VFP & KT-1350VFP pumps are supplied with vibrasprings which enable them to run quietly and vibration free. The pump 

can be operated on any flat, level floor which will support its weight. The pump must be installed on the vibramounts and flexible 

connectors fitted in suction, discharge, water and electrical connections. It is not necessary to bolt the pump to the floor

If the studs provided are not already installed into the vibrasprings, thread the short end into the top of the mount (smaller diameter) 

up to the spacer portion of the stud. With the pump lifted off the ground, screw the vibrasprings into the four open threaded holes 

in the flanged edges of the cylinder, in line with the bottom plate/cylinder bolts, at each corner.
