Lifesaver!!! I am not always able to print documents, fill, them out, sign them, and then scan them in and email them to recipients. This program allows me to skip most of the steps.

I've been using this app to help me…
I've been using this app to help me edit a workbook PDF that I am using for a course and it has been incredibly helpful. The only issue I am having comes to resizing text boxes, which can be rather cumbersome.

This program works great!
This program works great, sometimes things are a little off once you download and certain documents are easily editable while others can be a pain in the butt. Overall I like it & I think it's great. I would definitely use it & recommend it.

Really Great Software
I like that it's easily to fill in pdfs and also create fillable pdfs.

Excellent, efficient, immediate, professional service by *********. Very impressed with th level and quality of handling my request for refund as I only had to use the service one time, but let the "Free Trial" time frame lapse. The subscription charge was immediately refunded on the day it was debited for a one year subscription.

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
How Do Mechanical Seals Work? At the heart of why a mechanical seal works lies the rotating and stationary seal faces. Seal faces are lapped so flat it is impossible for a liquid or gas to flow through them. This allows for a shaft to spin, while a seal is being maintained mechanically.
What is the function of a seal?
Mechanical Seals in Centrifugal Pumps. The mechanical seal acts as a check valve and a slider bearing. The obvious function is that of a check valve to prevent liquid under pressure from leaking out of the pump, or from drawing air into the pump when under vacuum conditions.
What is the purpose of a seal?
A seal is a device for making an impression in wax, clay, paper, or some other medium, including an embodiment on paper, and is also the impression thus made. However, engraved gems were often carved in relief, called cameo in this context, giving a “counter-relief” or intaglio impression when used as seals.
How does a seal work?
Sealing Points The seal faces are pushed together using a combination of hydraulic force from the sealed fluid and spring force from the seal design. In this way a seal is formed to prevent process leaking between the rotating (shaft) and stationary areas of the pump.
Why seal flushing is required?
When you have specialized fluids that should not leak to the atmosphere or will not permit dilution with seal water, a double mechanical seal will be required and the flush plan will act as a miniature loop of barrier or buffer fluid. Barrier fluid is pressurized and keeps the product inside the pump.
Where are mechanical seals used?
They are used in various applications ranging from automobiles, ships, rockets and industrial plant equipment, to residential devices. Mechanical seals are intended to prevent the fluid (water or oil) used by a machine from leaking to the external environment (the atmosphere or a body of water).
Where are seals used?
Types of Industrial Engineering Seals Hydraulic seals are used to seal the opening between various components in the hydraulic cylinder. Pneumatic seals operate in dynamic applications, often at high speeds, generally with rotary or reciprocating motions. Piston seals are used in hydraulic cylinders for fluid sealing.
