Grumpy gits and useful tips: KARCHER LOST PRESSURE?
Sep 18, 2011 · Just an update, today I fitted a new upper casing of the pump which includes the detergent valve and I'm pleased to report I now have full pressure plus the pulsing of the motor has now stopped. I too purchased a replacement Karcher before deciding to attempt a repair so I now have two pressure washers!
This electricity-to-air converter is applied to the case where a signal current of 4 mA to 20 mA is converted into an air pressure signal of 20 kPa to 100 kPa (0.2 kgf/cm2 to 1 kgf/cm2) and a pneumatically controlled mechanism including a diaphragm type adjusting valve, etc. is …
Aug 10, 2021 · A diaphragm pump is a type of positive displacement pump which uses a flexible, reciprocating layer of plastic or rubber to change the volume of a chamber and force liquid through. While a centrifugal pump is designed to work continuously, a diaphragm pump uses a pulsing motion. This makes it ideal for metering liquids.

Mar 03, 2012 · 18.104.22.168 Gear Pumps. Gear pumps are rotary pumps in which two or more gears mesh to provide the pumping action. Usually one of the gears is capable of driving the other (s). The simplest form of this type of rotary pump is the gerotor pump.Figure 3.3.11 shows a typical gerotor pump configuration.
One of the most common ways to address pump flow pulsation in most pumps is to install a pulsation dampener. This piece of equipment is geared towards the pump it goes with and is often installed into the discharge line. As the pulsating flow enters the dampener, the air pocket trapped above the fluid can absorb up to 90% of pulsation.
