As more and more people use the used car, the transaction volume also increases. In the process of buying a used car, it is best to sign a contract with the other party for insurance and avoid unnecessary disputes in the future. However, in the process of signing the contract, what details need attention? Before the signing of a car purchase contract, the responsibilities of both parties and the consequences of breach of contract shall be clearly defined. If you do not write into the contract, you should ask the other party to add it, especially if you cannot transfer your car immediately after the purchase. You should indicate in the contract that if you fail the account, the other party will unconditionally return the full amount of the car regardless of the reasons. Or, after the completion of the account, the entire purchase price is settled. Timely transfer is very important, because if the unsettled car can't be settled without an insurance accident, all the expenses will be borne by you. Even if there is insurance, it will bring a lot of trouble to you and the former owner. It should be noted that if the car is found to be a problem car after purchase, it is necessary to submit the vehicle to the other party as soon as possible. Once in your hands for more than 3 months, the other party may deduct the depreciation charge and cannot refund the full amount. When signing the ordering contract, we suggest that you should let the other party to the specific conditions of the vehicle, such as ensuring that the car has no major traffic accident before the transaction, no water soaking, no safety hazards, etc., in the contract. Or attach a vehicle rating report from a third-party authoritative testing agency. Do not believe in verbal commitments. If the other party refuses to meet the requirements of the contract, it indicates that the car is more or less problematic. It is recommended that you cancel the purchase. Before signing, it is necessary to carefully read the words and phrases in the contract. If there are ambiguous statements, the expression is not clear and easy to cause content that has no solution, and it must be promptly corrected. To ensure that the content of the contract is easy to understand, both parties can understand it and clearly understand the responsibilities and obligations that must be fulfilled.
dredge pumps ranging from inlet diameters of 400mm up to 1400mm. Our CFD optimized pumps have an excellent suction performance, high efficiency, long wear life and require a minimum of maintenance. The pumps can be delivered in different types of wear resistant materials, and can be executed in a large number of different configurations.

Single-Walled Dredge Pumps Dredging Pump Dredge Pump,Dredging Equipment,Diaphragm Pump Unisite Group Ltd. , https://www.shipsparts.nl
single-walled dredge pumps are `all-round` and used in all types of dredgers. They are designed for typical pump pressures up to 16 bars, and can be excecuted with different types of pump seals such as: stuffing box, mechnical seal or hydro seal.
Double-Walled Dredge Pumps
double-walled dredge pumps are specially designed for high pressures, starting typically from 16 up to 30 bars. The double-walled pump design is based on the concept of pressure compensation between the outer-, and inner-pump casing. All types of configurations are possible such as 3,4 and 5 vane impellers, and casted or welded outer-casings.
Underwater Dredge Pumps
The underwater dredge pumps are used in cases where the highest possible suction performance is required. They basically have the same possibilities and options as our single-walled pumps have. Depending on our clients' preference they are executed with direct motor drive or integrated gearbox, with or without pressure compensation.
Casting
1)Pattern
Collection in our storehouse. Inspection of pattern in our workshop.
Pieces cast with wrong pattern due to insufficient inspection of pattern are rejected.
Free delivery of pattern (in good condition) with last cast piece of order to our client or stored in our workshop for future new production but with time-limited or quantity-bound.
2)Cast pieces
Material
The use of the cast pieces requires other chemical analysis and mechanical properties (unless otherwise mentioned on drawing).
Cast pieces group S (Wear) :
Impellers, pumphousings, dredge lines (bends, branchpipes, etc.)
Cast pieces group C (Construction) :
Other pieces as pivots, rod eyes, wire sheaves etc.

3)Inspection
Cast pieces are presented in our workshop, for inspection of dimensions and hardness after sandblasting and machining but before conservation and painting. Measurements are carried out by our services and deviations are sanctioned as follows:
At stress concentration area, MT&PT to check the crack, the qualified standard is no crack at these area.
