CHEMICAL PROCESS TRANSFER PUMPS FROM CHEMICAL PUMP AND VALVE MARKETING
Cost-effective from purchase and throughout entire lifecycle
Since the start-up of our company in 1984, the staff of Chemical Pump and Valve Marketing, who, between them have almost 60 years of experience in the pumping industry, has prided itself on the production of a range of locally manufactured chemical process transfer pumps that is not only cost-effective in the purchase stage, but thanks to the low running cost of the pumps, continues throughout the lifecycle of the pump.
The company's main aim, in fact, is to keep the cost of ownership as low as possible for its clients.
Product Range
The company's product range has been increased over time to include a full range of Chem-Pump pumps which are available in the following materials: epoxy resin, High Density Polyethylene, Polypropylene, 316 stainless steel and non-corrosive alloys.
The range of pumps includes horizontal long-coupled, horizontal close-coupled and vertical spindle sump pumps, which can be fitted onto a floating pontoon if so required. The company has also developed a chemical self priming/self-venting pump unit. The technical team, headed by one of the partners, Hennie Nieman, is always seeking out new products in order to increase the company's range, as well as engaging in ongoing research and development in the pumping industry.

ADVANTAGES
It is a considerable advantage of epoxy components that they are relatively light in weight. Another point of merit in the use of epoxy components is their relatively low cost. Certain corrosive chemicals which are generally processed in contact only with expensive materials such as titanium, may well be amenable to epoxy components. Epoxy resins withstand combined heat, abrasion and corrosion better than any other conventional plastics.
The process for making metal parts of similar performance may entail a number of processes such as welding, stress relieving, machining and rubber lining, and this inevitably raises the cost.
For epoxy-based components the same homogenous material is used throughout. All external surfaces, as well as internal ones, are therefore corrosion resistant and relatively free from maintenance requirements. This means that the plant is of clean and pleasing appearance.

HYDRAULIC FUNDAMENTALS
Pressure: The basic definition of pressure is force per unit area. As commonly used in hydraulics and in this website, it is expressed in pounds per square inch (PSI).
Atmospheric Pressure is the force exerted on a unit area by the weight of the atmosphere. At sea level, the atmospheric standard pressure is 14.7 pounds per square inch.
Gage Pressure: Using atmospheric pressure as a zero reference, gage pressure is a measure of the force. per unit area exerted by a fluid. Units area PSIG.
