Warehouse management, the first step for a good service

A good sales service for a chemical pump company does not depend only on how the sales office or the customer service interact with the client but many more factors plays an important role on the satisfaction of the customer. We can say that all the pump factory management has an impact on the sales process but one of the factors which has a direct impact on the customer is the warehouse management of pumps and spare parts.
Having an organized and well managed warehouse is the first step for a good service to the customer from the first quotation to the supply of spare parts for the pump maintenance. As a matter of fact, if the stock situation is clear it is possible to indicate in all the quotations precise delivery dates so that the customer can correctly schedule the pump installation. After placGemmeCotti warehouse managementing order, the customer can be informed step by step about the status of the pumps, if the pumps are ready on stock or if the delivery can take some days. Moreover, it is essential to have the main spare parts always on stock in case of urgent orders of pumps or spare parts for maintenance and repair, in this way the customer can receive the products quickly and avoid useless long plant shutdowns.
GemmeCotti pays great attention to the aspect of the warehouse management but many companies ignore this part because it is considered a waste of time. This choice can seem true on a short period of time, but in the long run there will be many problems with consequent bigger waste of time to solve issues caused by a poor management. If a company wants to develop, the warehouse management is really important because, in addition to the positive aspects for the customer, it avoids excessive capital being tied up, optimization of the available space and on the long run a cost reduction.
First of all it is necessary to codify all the parts and keep tracks of the quantities. Then the parts should be rationally organized to make the management more rapid and effective, in addition to the obvious space optimization and cleanliness.
Once the warehouse is well organized it is also very important to keep the everything in order. To do so, a software can help the management of the stock but it is important to choose the right software in accordance with the real needs of the company in order to get more benefits.
The warehouse management in GemmeCotti has recently being checked and improved for an even better service to the customer and a bigger pumps availability on stock. If the customer is in urgent need for a chemical pump, we are ready to satisfy him in no time.

Pressure vs head, what is the difference?

The pump selection of a pump is driven by the following main parameters:
– Head (H)
– Flow rate (Q)
– Fluid characteristics (ρ, γ, T ….)
Sometimes head can be confused with pressure during pump choice. As a matter of fact there is a strict relation between them which is defined by the fluid specific gravity, so the relation is fluid dependent. So what is the difference between pressure and head?

Definition of head and pressure

Head is the height given by the pump to the fluid and it is measured in meters of liquid column [m.l.c.] or simply indicated in meters [m]. The given head is fluid independent: different fluids
with different specific gravities are all lifted at the same height.
Pressure, instead, is fluid dependent and it is affected by the liquid density. In fact the force of a fixed height liquid column over a unitary area will change with different specific gravities. So in this case the same head generates different pressures.

Measurements: Pressure or Head?

Head is not directly measured. Manometers on the pump suction and delivery line give the measure of the pressure. Measurements given by manometers indicate differential pressures imposed by the pump between suction and discharge. These measures are read in [bar] [atm] [psi] [ft H2O] etc.. Specific gravity γ has to be considered to evaluate the correspondent head.

Conversions & Practical Example

As stated before, the same pump at the same working point will give always the same head with different pressures in accordance with the density γ of the working fluid.
For example, a mag drive centrifugal pump HTM 10 working at a given point Q= 7.5 m3/h H = 10 mlc operating with water and concentrated H2SO4 gives the same head (H=10m) to water ( γ= 1kg/dm3) and to sulfuric acid (γ = 1.8kg/dm3), while measurements of differential pressures between suction and delivery will be:

equazione pressione 12

The mathematical relationship is reported in the following equation:

equazione pressione 1
Also power consumption is influenced by the previous relationship of pressure, as:

equazione pressione 2curve pressure

Notes for technicians

– Previous relations are valid for low viscosity fluids (water equivalent), along with increasing viscosity, pump performances have to be reduced using pump derating rules.
– At a fixed rotational speed a centrifugal pump generates head related to the flow rate following its characteristic curve.
– The computation of the needed head that should be delivered by the pump, is not so straight as the evaluation of the desired height difference. Needed Head is composed by the following terms:

  • Geodetic head: difference between suction and delivery height expressed in meters of liquid column

equazione pressione 3

  • Difference between absolute pressure of the delivery and suction reservoir

equazione pressione 4

  • Distributed and concentrated friction losses also expressed in m.l.c.

6 reasons to choose GemmeCotti chemical pumps

For more than 20 years we have been pursuing one main goal: design and produce magnetic pumps which meet the customers’ needs. That’s what drives us and makes us world-leader in the field of chemical pumps. So what are the characteristics of GemmeCotti pumps which make them unique and so appreciated by customers the world over?

1- Wide range of pumps among which the customer can choose. We have more than 400 pump variations so that we can always offer to the customer the right solution for his application. Each pump is customized according to many variables:

2- High quality pump materials. It’s important for us to offer the highest quality possible that’s why we choose only the best materials (Polypropylene, PVDF and AISI316) which can resist corrosion and which are suitable to pump almost every existing chemical. You can check out our chemical compatibility chart for more information and to select the right pump material for your application.

3- Best pump design for pumping chemicals. Magnetic drive pumps have a simple sealless design which is the ideal solution when handling chemicals and acids. The hydraulic part of the pump is hermetically closed so there is absolutely no leakage and emission of fluid. This is an essential characteristic because mag drive pumps guarantee safety for both workmen and the environment. Moreover the absence of any seal makes the pump highly reliable eliminating the maintenance and repair costs.

Typical pump design: The external magnet of the pump is placed on the motor shaft and when rotating it transmits the motion to the internal magnet thanks to the magnetic attraction of the two joints. The internal magnet is connected to the impeller which spins and moves the fluid through the pump. The external magnet and inner magnet are separated by a rear casing that creates a hermetic containment of the liquid that has no access to the outside.

4- Chemical pumps completely Made in Italy. We are an Italian manufacturer and we are proud to offer high quality pumps designed, assembled and tested directly in our workshop. The pump parts are made and machined by our Italian suppliers all located near our factory. So, for us, suppliers play an important role in the resulting quality of the pumps. That’s why we choose and qualify them through a strict qualification process and we keep a close relationship with everyone in order to assure the highest quality of each pump part and consequently of the complete chemical pump assembly.

5- Every pump is checked and tested before delivery. What is the best way to assure the pump quality than try it personally? We perform rigorous tests during the whole assembly process according to ISO9001 based quality control standards. That is not all. We want to achieve zero defect rate, which is why we test every single pump at our test bench before delivery to our customer to check both the performances and the correct functioning.

6- Chemical pumps suitable for many applications. GemmeCotti industrial pumps can be used in various applications where chemicals, acids, dangerous liquids are involved, such as: chemical industries, waste water treatments, galvanic industries, surface treatments (zinc-plating, silver-plating, coppering galvanic treatments, chemical nickel plating) in machines and equipment for the printing industry, in machines for tanning industries, for printed circuit boards production, in scrubbers, air treatment plants, petrochemical and oil & gas industry, for biofuel handling, in textile industry, food industry and in bottling machines.

In Gemmecotti we believe in Equal Opportunity to build the future

In our Company 45% are women and 55% are men. Women aren’t relegated in minor roles as happens often in our country. In our team women have important decisional roles because we believe in Equal Opportunity principle.
If people , regardless of gender, feel themselves recognized for their expertise and are free to express their potential, the whole company will benefit.
Women have grown in our company and they were able to grow our business over the years.
That’s why in GemmeCotti women occupy decision-making roles and have responsibilities and that ‘s why you will find female staff always professional and competent even in sales department that is often dominated by men.

In Italy there are many laws on Equal Opportunities ,( Code of Equal Opportunities between men and women ( Legislative Decree 11 April 2006 , 198 ) ), especially thanks to the important imput derived From European Norm that inserted Equal Opportunities between the Fundamental Principles. ( Charter of Fundamental Rights of the European Union , Nice 2000 , art 21 , art 23).

The company plays an important role in the application of the principle of equal opportunities , but often it is left to the voluntary initiative of the entrepreneur that is not supported by the institutions. In our country woman are paid 20 % less then men for the same job and many are the discrimination against women so we believe that it is important to talk about Equal Opportunities.
