Open Impeller System

Open Impeller System US Patent: #9957979
Drive End Socket Set US Patent: #D823658 S

The open impeller wrench set allows the craftsman to safely remove damaged or sharp-edged impellers without the risk of injury or the possibility of causing further damage to equipment. They are designed to allow the craftsman to engage the wrench in a manner that allows both hands to be free to apply torque to the system. The wrenches are designed to fit impellers with an even or odd amount of vanes. The wrenches engage in a way that distributes the pressure evenly around the eye of the impeller. This applies an even force of torque to the assembly making the most difficult to remove impellers much easier to break loose in a safe manner.

For machinists and other craftsmen who work with pumps, you know how difficult it can be to repair an open impeller pump. These expensive, heavy-duty pieces of equipment can get damaged easily if proper tools aren’t used. If you regularly work with an open type impeller, now you have access to a wrench system that will make repairs simple, painless, and safe for both you and your machinery. Our KIRIS System (Key Impeller Removal and Installation System) is a groundbreaking system designed to help you maintain your impeller pumps.

When making repairs to an open impeller pump, it’s easy to make mistakes that can end up warping the vanes of the impeller. Once damaged, this can eventually lead to premature pump failure. KIRIS helps you prevent these user errors and allows you to get the work done without touching any sharp-edged impellers.

Our wrench system works by evenly distributing pressure around the eye of the impeller. This enables an even force of torque to allow the impeller to simply pop off in a manner safe for the components of the pump as well as your hands.

Your KIRIS wrench system has all the tools you need to repair your ANSI centrifugal pump. In your KIRIS kit you will find the following components:

• • A wrench for the odd number (5)vaned impeller
  • A wrench for the even number (6) vaned impeller
  • A 3-piece input shaft socket that fits all standard sizes and keys

To use your KIRIS wrench system, start by removing the coupling hub & key from the pump. Once removed, select the correct size input shaft socket from your kit. You will also want to take the corresponding key that matches the pump size. Place the key on the drive end of the shaft and the socket on the shaft.

Next, depending on the number of vanes on your pump, select either the even vane wrench marked (EV) or odd vane wrench marked (OV). Line this wrench up with the impeller and turn the drive end socket on the other side. Place a wrench on the squared end of drive end socket, then manipulate the shaft in the opposite direction of the impeller. This should enable the open vaned impeller to pop right off. When you’ve finished, you will just reverse the process to reassemble.

Our KIRIS wrench system is a comprehensive kit that enables you to easily complete repair jobs on a centrifugal open impeller pump. Safety and ease of use make this the only kit you need to get the job done right and keep your pumps maintained in good working order for years to come.
