Other parts: PVDF (polyvinylidene fluoride)
Non-slip torque transfer
Liquid level up to 5 m below the pump
Max. output rate: 200 l/min
Max. discharge head: 27 m
Suction head: up to 5m max.
Motor power: 0.25 - 2.2 kW
The S Pump Series has a special pump housing with a collection container that serves as a liquid reservoir. After filling the liquid container, the pump creates a strong negative pressure and is so enabled to independently prime the medium. In the S Pump Series, the motor power is transmitted without slip directly to the pump impeller through a solid shaft. A mechanical seal prevents the leakage of the media to be pumped and ensures the leak proof sealing of the centrifugal pump.
Advantages of the S Pump Series:
self-priming, the liquid level can be up to 5 m below the pump
offers a high degree of operational safety
the highest chemical resistance
robust, thick-walled design
low-maintenance through an optimal adaptation to the medium to be pumped
long-lasting and wear resistant, various types of designs for almost all operating conditions
models are also available, where no metal parts are in contact with the medium
easy to maintain (wear parts and the mechanical seal can be changed swiftly)
universally applicable, quiet and compact
various chemical resistant materials can be supplied from stocked inventory
The S Pump Series is especially conceived for the self-priming operation. Therefore, it is particularly suitable if frequent starts with an empty suction line are necessary or the penetration of gasses cannot be prevented. The design and manufacturing materials allow for optimized adaptability for the many different operating conditions as well as for the various media to be pumped
This results in application possibilities, amongst others, for the following application fields:
Sampling or the transmission out of containers
Pits or plants
everywhere, where the technical safety regulations do not allow the application of normal priming pumps
Materials and Components
Main material: Parts made solid of PVDF, PP or PVC
Medium temperature up to 50° C possible
Elastomere alternatively made of FKM, EPDM, FEP or Kalrez®
Shafts are made of stainless steel or Hastelloy C4
Mechanical seals made of PTFE, ceramic, carbon or SiC
Structure in the designs A, B and C:
Design A: No metal parts in the pump are in contact with the medium. The impeller is equipped with a shaft sleeve. The face pressure is achieved with a thrust-collar-loaded mechanical seal.
Design B: The mechanical seal is spring-loaded. The impeller is equipped with a shaft sleeve. The spring is made of Hastelloy and in contact with the medium; however, the shaft is not.
Design C: The mechanical seal is spring-loaded. The impeller does not have a shaft sleeve. Simple, robust structure.
The metal parts that are in contact with the medium (shaft sleeve, impeller insert and locking nut) are available in stainless steel or Hastelloy.
High-quality electric motors made in Germany
PVDF: Polyvinylidene Fluoride, Pure, milky white, not colored (up to +95° C)
PP: Polypropylene, Fiber glass-reinforced, gray (up to +80° C)
