The gauge is filled with some liquid

Question

We have purchased a KBT pump ПМЭ-710-1к. The gauge is filled with some liquid. Should it be so?

Answer

Yes. There is glycerin inside the gauge. It is done to minimize the possible tremor of the arrow caused by differences in pressure or by equipment connected to the pump. The gauge is not fully filled with glycerin, there is always some air inside.
The pump ПМР-7020-К2 does not have an auto pressure relief valve

Question

The pump ПМР-7020-К2 does not have an auto pressure relief valve. How can the pressure be released after the operation cycle is completed?

Answer

Turn the distributor to the counter position to release pressure.
Pressure is built up slower than before

Question

After some time of working with the pump ПМР-7020- К2, we have noticed that the pressure is built up slower than before. What is the reason for that?

Answer

One of the reasons for that is an open breather, that should be opened by 1\4-1\2 turns so that you also prevent too much air inside the pump.
The pump ПМЭ-7050-К2 does not have a distributor to change the pressure flow from one channel to another

Question

The pump ПМЭ-7050-К2 does not have a distributor to change the pressure flow from one channel to another. How can the oil supply be changed to the other channel?

Answer

The control pedal of the pump has two modes: position 1 for pressure supply to one channel, position 2- for pressure supply to the other channel. If you want to change the channel that gets the pressure, press the pedal aiming at the other position, it will cause pressure release. Only one position of the pedal can be active in pumps ПМЭ-7050. A simultaneous supply of pressure to both channels is impossible in this type of pump.

I would like to have a high pressure hose longer, that is in the set with the pump ПМЭ-7050

Question

I would like to have a high-pressure hose longer, that is in the set with the pump ПМЭ-7050. What will I need to ensure a tight connection of the hose with the tool and the pump?

Answer

The high-pressure hose should have quick-release valves at both sides. Use a thread-fill tape to ensure properly sealed connection.
The pump ПМН-7012 does not have any valve to release pressure by hand

Question

The pump ПМН-7012 does not have any valve to release pressure by hand. How should I release pressure when the working cycle is done?

Answer

Can I use two or three tools simultaneously with the help of hydraulic distributing tap КГР-3?

Question

Can I use two or three tools simultaneously with the help of hydraulic distributing tap КГР-3?

Answer

Yes, but you should take into account the total oil volume for all tools and add some volume that needs to be inside the hoses. You shouldn’t also forget that the time of the working cycle can differ for different tools.
